We got a good rate at this Courtyard for October but also have a back up reservation for Universal Endless Summer resort. I'm still deciding which of the two reservations to cancel. Is the parking really a problem at the Courtyard? We always have a rental car and come back late to the hotel and I definitely don't want to deal with a full parking lot.
The concern I read was mostly that it was difficult to exit the parking lots in the morning when trying to get to WDW, but that is just my recollection of reviews I read.
If you want a fun pool: Marriott World Center, Gaylord, Swan/Dolphin, and Caribe Royale all have fun pools. All the Universal hotel pools are super except the Aventura, and obviously we have not yet seen Endless Summer. We very much enjoy Sapphire Falls! It looks like the Endless summer pool maybe has zero depth entry, and poolside activities, but no slide. Guests staying at the US hotels are allowed to pool hop, but I suggest Cabana Bay, Sapphire Falls, or MAYBE Aventura if you want a mid-price hotel with a fun pool. Aventura has great food court, and it is a short walk to Sapphire Falls.
When we were trying to describe the Aventura, the word that kept popping into our head was, "millennial." Devices in the room are controlled by an iPad, and we loved all the VERY 2019 food court custom meal options. Even the prepackaged snacks were very 2019: dried fruit, granola bars, etc., and a variety of 2019-milk options. such as soy milk.
Sapphire Falls has lots of blue and white, is very clean and very relaxing. The pool is fun, and we liked the food options we tried. The quick service place isn't huge, but it has a good variety of good food options. They have yogurt/fruit smoothies, nice looking salads, a good variety of sandwiches/panini, ice cream, a rotation of daily specials, and good coffee.
You also get access to all of Citywalk. Cabana Bay and Endless Summer are mostly served by buses. Aventura has buses. Sapphire and the 3 deluxe hotels are served by frequent shuttle boats and walking paths.
