We have decided on two nights in Oslo. We will stay at airport and take train into town on Monday for sightseeing.
We will stay one night at Keflavik. We will rent a car when we arrive and see how much we can see; starting with Blue Lagoon. Also looking at a flight seeing trip to the north to see waterfalls.
Norwegian Air doesn't work too well for us; we have to either get to NYC or Orlando. Icelandair has same issues. Will see what options delta has for us.
