We stayed at Poly. Isles for our very first ever time staying in a resort, so our opinion may be a little overrated. But, we loved it. I loved the theme, everything about it made me know I'd never stay in a hotel again! It was well laid out, the table was set elaborately, it was well stocked in the kitchen. Now, this is going back a few years, so I can't remember much about the other details, but I do remember it being one of my favorite vacations. Now, it's an older resort, so it's kind of sad that you will then be comparing it to your next stay at Bonnet Creek because Bonnet Creek has a lot more to it. It's just more of everything as far as pools and activities, etc. But, I personally like the smaller resorts because I like not having to hike a great distance with my kids to get to the pool area or to an activity, etc. I think you will like both of them very much for what they can offer. I'd use Poly. Isles as a week to relax and enjoy the calm environment and peace of the resort and then use Bonnet Creek for the pools and other activities. HTH!! Have fun!! BTW, I like the theme of P.I. better than B.C.
