Well, thanks everyone. You've been great and this has all been very helpful.
So yes, I will go to Iceland for 4 days. I will base myself at a hostel in Reykjavik (all I can afford), and I'll do 2 day trip tours, still researching which ones but those recommended look great. And I love hot springs, so I plan to soak the evenings away after enjoying the "youth scene" over there. I need to check out a good Icelandic beer. Any recommendations.
And I will visit Iceland at the of my trip, rather than at the beginning, to take advantage of that extra sunlight!
I'm pumped about this!!
