Norway was beautiful and it was a pleasure to be able to absorb our surroundings comfortable in the knowledge that we were in safe hands. The small group size made the tour feel quite personal and we got to meet some great people. Special credit to our tour guide, Line. She was very professional, an excellent conversationalist, very well traveled and made all the details that would normally frustrate us (timetables, transportation, etc,) seem quite effortless. During the course of our tour, we also met two other employees of Nordic Visitor (Bjorn and a woman whose name escapes me.

We have recently completed the 9 day Natural Wonders of Iceland Tour with Nordic visitor and were very happy with our tour. We were a little apprehensive initially about booking with an unknown operator. Coming from Australia, there is not a lot on offer from travel agents. Mostly overpriced tours, that did not seem to offer value for money in comparison to this tour and with some the hotel accommodation details were not provided which made us very nervous about booking with them.

We normally would prefer to do our own self drive tour, but driving on the opposite side of the road with possibly icy roads, had scared us into booking a small group tour and in hindsight we are glad we did. Although the roads did seem on the most part to be fairly easy to navigate, it was very relaxing to let someone else take care of transporting us between the beautiful locations. We were extremely lucky with our tour guide 'Rakel', who was absolutely wonderful.

She made our tour even more amazing with her funny commentary, patience, and warm personality. The tour itself was nicely broken up, with plenty of breaks, and a little exercise most days. Our tour guide was very accommodating with the walkers of the group and would organise extra impromptu walking time whenever we got the chance.

We were particularly grateful for that, as it allowed us to eat all of the delicious three course meals each night, with a relatively guilt free conscience. The bus itself was comfortable enough, however might be a little compact for particularly tall people or large framed people.

Our accommodation on the whole was very good. Every hotel was spotless, with comfy beds and warm showers. Some were in more striking location than others, but we did not have a bad experience at any of the hotels. My partner and I have just returned from three months travelling around Europe with one of our stops being in Iceland for 3 weeks. We booked to drive around Iceland for 2 weeks with Nordic Visitor after booking a trip with them to Greenland. Iceland we have to say was the highlight of our trip.

The fact that the car, hotels, activities were arranged prior to us landing was a great time saver. The welcome pack was a very pleasant surprise. All in all we will definitely be using Nordic Visitor for our next trip to Iceland.

We are older adults, and have both traveled extensively. We adored Iceland, and we both agreed this was the BEST trip we have ever taken. You were absolutely amazing from the beginning till the end. All the hotels were awesome with its great views. Recommendations provided for food and sights to see were great.

Providing phone and hotel contacts were great so we could inform them we would be checking in late. We had a lot of questions in planning for the trip and Dagny was there with us throughout the process answering every question in detail patiently.

This couldn't have been a better experience :) We highly recommend using NV services. The little gems along the way were a great touch. We really enjoyed the secret hot springs and homemade ice cream (Efstidalur) that Arnar made notes of on our map.

The map with the highlighted routes and stops was a lifesaver. The planning and prebookings were also a relief so everything was along the way and easy to get through. Overall, we were impressed with how well planned everything was. All the guesthouses we stayed in were very very comfortable. Much better than we had expected and the owners were all lovely. We always had a good home cooked breakfast and sometimes a dinner was provided at a cost of course. We were so glad we had chosen the "budget" accommodation to experience being in someone's home and meeting others staying there.

Would highly recommend this type of accommodation. Found driving around Iceland quite easy.

Five years ago, traditionalists decried influencer marketing as a fad that would not last. How wrong they were. While print advertising was already fading, television advertising was king. It is amazing how much has changed in the world of marketing in just half a decade. We are now in 2017 and influencer marketing is far more than just a buzzword. It has become the de facto way to reach the savvy and cynical youngsters of Generations Y and Z. The influencer model is now maturing, as more refined methods are put into practice, platforms are becoming more iconic, and agencies realize that they need to jump on the influencer marketing bandwagon or else they will be left behind in the marketing Dark Ages.

So, how do we at the Influencer Marketing Hub expect influencer marketing to evolve over the remainder of this year.

Here are our predictions for influencer marketing in 2017. Influencer marketing grew out of celebrity endorsement.

It would be like trying to use Madonna to promote your range of heavy duty power tools - or Ronaldo to promote your opera glasses. They are micro-influencers - people who have high engagement and huge followings in a relatively niche area of interest. We believe that 2017 will see a huge increase in the number of brands working with micro-influencers. Big brands will continue to work with celebrities, although even they will try to better align their brands with celebrities who are more relevant to their product.

However, the bulk of brands will focus on working with laser-targeted micro-influencers. Celebrity influencers have always been paid - in many cases extremely well - to promote brands and their products.
