I left ASA a while ago, but some nice overnights-
Canada- Ottawa- very nice city and overnight as with Montreal. Toronto- you stay at the airport, so nothing to do.
Ft. Walton has been nice, depending on the hotel.
I can't remember them all, but some times I was surprised by overnights in towns that I thought were dumps, but turned out to be nice. We used to stay at a very nice hotel in Augusta, GA, for example. The area was kind of dumpy, but nice hotel. They had a happy hour for crew members on the roof some nights. Very nice breakfast in the morning.
As long as the hotel is safe and clean, and in an area with things to do I was happy. I found that some crew members would complain if they were in the best hotel in a great part of town in a city with lots to do because there was not a McDonalds across the street.
