We stayed at the Cabana Bay last year. The food there is expensive and ordinary.
Our favourite places to eat were Pei Wei and Sweet tomatoes. Both were counter service and the food was really nice. DD is vegetarian and both these places had loads of veggie food, something that was surprisingly difficult to find in Florida as they often add things like bacon to what is a traditional veggie dish.
The rooms were very comfortable, and the beds even more so, but I really didn't like the public areas. The 1950s music loop that is played all the flipping time soon loses its novelty, and the plasticky canteen furniture in the eating areas makes it feel like a school canteen.
We ended up getting coffee and croissants from Starbucks for breakfast most days and taking them back to our room.
We ate at City Walk loads of times, but not at Toothsome. It is expensive to eat at any of the waited on restaurants there, and alcohol is expensive.
The shuttle bus from the hotel to Universal was a godsend and very regular. TBH I would struggle to do your holiday without a car. We drove to all the Disney parks, Kennedy Space Centre, Boggy Creek, Walmart, Pei Wei and Sweet Tomatoes. There wasn't anywhere within walking distance of the hotel.
We could have walked to Universal, but in 36 degree heat and high humidity we would have been utterly drained by the time we got there.
I will come back later and tell you where we had some lovely meals at City Walk.
