Hi Alex
THE LAND OF FIRE AND ICE
I went for 5 Days with BMW in February a few years ago
We Stayed at the Hotel Borg. Very Central Close to nice Bars and eating places.
We were looked after by a company called
http://mountaineers.is/They collected us from the Airport in Monster Trucks.
Took us straight to the Blue Lagoon did all the tourist things and was very well looked after
Mate they would advise what to do.
A Helicopter ride is cool flying across frozen Lakes about 6ft high.
We used the company that filmed James Bond Die Another Day
If you chose these 2 you won't go far wrong.
Regards
M
