Never been to "Q" but I've read tons of blog posts. It seems like a fun place but I can't believe it could compare to the Florida Keys in the winter.
We have been going down to the every winter for the past several years. We liked it so much we bought an rv lot there near Key West.
Key West is crowded and crazy, and it takes a little getting used to, but it's a super fun place, especially during the nightly sunset celebration.
We find the lower Keys (from Big Pine Key and down) to be less crowded. It's crazy up towards Islamorada and Marathon, but nice and quiet where we are on Cudjoe Key.
Check out my blog if you want to see all the fun things to do in the Keys. Here is a link for a fun night in Key West, but there is so much more. Never a dull moment.
