Sailbum, thanks for your info. Our lodging itinerary is just about set, finding places for 3 adults last minute has proven interesting, but doable!
There will be short driving days and very long ones, but it's all about the journey and with the 24 hours of light it should be awesome!

3 nights in a cabin up 35 towards Gulfoss falls. 3 days to cover Golden Circle and all the sights to Vik.

1 night guesthouse near Hofn, Skaftafell National Park and Glacier Lagoon etc.

1 night farm stay east fjords, Horseback riding, maybe boat trip.

1 night small cottage on a stream just outside Egilstadir, Sightsee east fjords.

1 night Guest cottage in Akureyri. on the way visit Myvatin geothermal area and Selfoss falls area. maybe morning Whale watching trip.

1 night "somewhere" between Akureyri and Reykjavik...tough decision.

2 nights in Air bnb center of old town Reynkovik to slow down again and relax, Brew pubs and coffee houses! Saving Blue Lagoon for last full day.


Any additional tips would be appreciated!
