After about 20 hrs total online (TA, expedia, hotels.com, etc) I finally made a decision! We're staying at Bungalow Beach Resort Aug 1-4 in room 102. I couldn't decide between Sanibel, Captiva, AMI, Siesta Key, Lido, Longboat, etc. I finally made a decision today that I just had to figure it out. So I went with my gut on this one. I'm crossing my fingers ... but I'm also very excited and looking forward to our trip.
I couldn't decide what I was looking for (laid back, resort, condo, etc) but since we're only looking for 3 days, that narrowed it down a lot. A lot of places wouldn't book for that short of time period. Since we're headed to the Hilton Clearwater for a meeting for about 5 days after we leave AMI, I thought it would be best to go with the "laid back" vacation plans. I can do the tiki bar thing once I get to the Hilton.
So, thank you very much for everyone's helpful advice on the forums! I really appreciated the help.
