Just back from the Country Inn & Suites in Kissimmee, it's also listed as "at Calypso Cay" or "Maingate."
It was a great choice for our family (two adults, kids 10 and 7.5). We had a 'kids suite' which meant a king bed and TV for us, twin bunkbeds and another TV for the kids. The kids area was nicely decorated with a pirate-y beach-y theme, and they each had a loft bed with drawers underneath as opposed to traditional bunks.
The breakfast was fine. Yes, the salesmen came in on weekdays, but we avoided them by eating outside. I was more put off by the 2 TVs on different stations AND stereo music playing. Talk about sensory overload!
We were on the 2nd floor so could walk up and down most of the time, a nice benefit since only one elevator seemed to be working.
Kids loved the themed pool. I used the adult pool once and dh went in the hot tub a few times. He also had a beer by the pool one hot afternoon. It's a nice option.
We tried the mini-golf, but got too darn hot (record heat wave in Orlando last week). I think on a cool evening it would be enjoyable.
This location is very convenient to a SuperWalmart, Super Target and the usual chain restaurants on 192. The room had a mini-fridge and a microwave which we put to good use for popcorn.
The staff was polite, room was clean, beds were comfortable etc. As I said, it really worked out well for us.
