We travelled with two grandparents, two parents, and a 3yo and 7mo. This property was ideal for us!
The Master was large enough for the crib to be set up and still have room to walk around.
The high chair was clean and easy to use.
We did not use the larger stroller that was provided, but there were several umbrella strollers in the pantry which we did use (one). There was a toilet seat for younger children in the main powder room that was perfect for my daughter, and the sinks were low enough that she could reach to wash her hands without help.
Do expect to have to do a run for essentials like hand soap and toilet paper while there.
I recommend checking the weather before getting there; if it is expected to be below 15C for the bulk of the time you're there, don't bother passing for heating the pool... The heater can't handle the "cold". We were lucky to have the water get up to 82F once while we were there, the rest of the time it hovered around 75F, not good swimming temp. This would probably be a problem with any heater in Florida, not just this one.
The washer/dryer were great and HUGE. Double check for detergent before you go shopping. We accidentally bought some when there was some left behind!
They have lots of towels, so don't bother bringing swimming towels.
There's some baby toys in the crib that we didn't use, but they were a nice surprise.
Lots of books under the TV.
Comfortable beds and furniture in the house. As someone with a back injury, it was so great to be able to relax and not have problems.
There were stairs up to the four bedrooms, so if you have mobility issues involving stairs, I'm afraid this is not a good option for you.
Overall, this house was perfect for our needs and I highly recommend it (and did recommend it while I was still there!).
