Villa Location

I booked a stay for my friends at Sheraton Vistana Villages. Can someone tell me about the various phases of the resort, and which areas would be worth requesting ahead of time? They have three children, ages 3, 6, and 8 years old... so being close to a pool area and children's activities would be ideal. Also, if they would rather have a two bedroom vs a two-bedroom lock off, is that an easy request to fill?

Thanks!!!

don't get a lock off, it is meant for grandparents the kids would be locked off from parents. go for the 2bd so you have 2 queens beds for the kids in 1 room and separate room with 1 king for parents
