JW Marriott Scottsdale??

Hi all. We made tentative reservations at this resort today for spring break in late March. There are 2 families travelling with a total of 7 children. We've rented 3 rooms which are called "Casitas". I have 2 questions for anyone whose stayed here recently. I am confused as to what pool(s) are on the property. Some reviews mention a big pool, some mention a deceptively small pool, and I see a pic on their website of the "spa pool". So, anyone know what's there for our children? We'll do lots of hiking, outdoor activities, but definitely want a decent sized pool for them to enjoy also.

Secondly, are the "Casita" rooms basically just a bit larger hotel rooms with small refrigerators? The childrens' food will be included in our room rate, but trying to determine what the difference is between this room and a regular hotel room. Thanks in advance for any clarification!
