Yes. The Al a Carte restaurants are at night so that's why you probably cannot eat at those.
If you have Messenger, you can message them directly and ask, I am sure you can, as well as Chayita the burrito place next to the Cupcake Cafe. They are good about answering back promptly.Edited: 7:47 am, June 07, 2018
I've never stayed at Caracol, so I can't answer your question, but if you can eat at the burrito place, I highly recommend it. It's excellent!
I’m here now at Sandos Playacar and went to Sandos Caracol today so we checked the rules. You can eat lunch and dinner anywhere but not breakfast. We used the Italian al a carte at Thexsisyer hotel today for lunch. Everything is included except the taxi fare! Just remember to take your towel cards and get the towels at reception when you arrive so you get the right card fs back!

See. Go there after Xplor.
We have more that a dozen combined visits at both resorts. You'll have access to the buffet which is fairly new and very nice. I know it's down on paper somewhere the "no visiting until after 11" or something like that but we go fairly early in the morning and have never had an issue. Of course the buffet serves breakfast as well. You'll also have access to the Cupcake Cafe, Chyita (burrito bar) and the snack hut on the beach (burgers, hotdogs, fries, etc). I say it's worth a visit just to see the beach which is fabulous. Enjoy your vacation!
