Hello Laura and thanks for bringing such an interesting question to us here at the Disney Parks Moms Panel.
I have some very happy memories of my own previous family trips spent within the lush islands at
Disney's Caribbean Beach Resort and like you I simply can't wait to return to check out everything Disney Imagineers have created for us Guests to enjoy!
I'm happy to share that to the very best of my current knowledge
Fall 2018 is still set as the scheduled opening time for the 2 new dining locations at Old Port Royale which are Sebastian's and Centertown Market and even though I don't have any exact dates for soft openings I'm quite sure everything will be revealed fairly soon via the Disney Parks Blog.
However I can say the Quick Service
Spyglass Grill is certainly worth checking out and can be found located close by to the Trinidad South Pool Area - I know I'm eager to try some of the delicious looking tacos as featured in this past
Disney Parks Blog.
You're sure to find some tasty treats at the
2018 Epcot International Food & Wine Festival where you may be even able to discover some further Caribbean culinary delights as you eat your way around World Showcase - look for
Islands of the Caribbean stand to the left as you enter World Showcase Plaza.
Have a great Disney day.
