Hi Julie, Thanks for visiting the Moms Panel!
I've stayed in All Star Sports as well as the Caribbean Beach Resort. To be honest, I would choose a Value Resort like Pop Century over the CBR when traveling with a 5 year old girl.
The Value Resort rooms are bright and cheery. In addition, the food court, gift shop, lobby and bus stop are all in one central location (which is relatively close to the rooms). At Caribbean Beach Resort, some of the rooms are a significant distance from all of these. In fact, the food court and lobby are in two different places (which can require inter-resort shuttles to get to depending on your room location). My room was a 10 minute walk from the food court and main pool.
I would choose a Value Resort and use part of $100 to treat your little Princess to pampering at the Bibbidi Bobbidi Boutique inside the Magic Kingdom instead. See
HERE. Our 5 year old daughter absolutely loves it.
Hope this helps and that you have a magical vacation,
Kaylene
