Helen-
The Silversea itinerary says we arrive in Reykjavik at 7:00 a.m.. I bet we can debark not too long after that. Alice and I will just see what we can see of Reykjavik in the few hours we will have there that day before our 5:30 pm flight. We would love to stay in Iceland longer and do a trip like Brad and Leslie did a few years ago. But we will need to do that as a separate trip.
I booked hotels in Oslo:
Hotel Continental for two nights.
Radisson Blu Airport hotel for the last night
