Marc, if you're still interested I just booked what seems like a very good deal for a day room when we arrive in Anchorage on September 6th.
The Hawthorne Suites has day rooms available for half the regular rate. The regular AARP rate is $90 so they only want $45 plus tax for the day room. And they said it's likely that I could get into the room at noon. The hotel even has an airport shuttle.
Hawthorne Suites is a national brand. It can't be that bad, especially for $45. Tom.
