UPDATE: I spoke with RCL and kids will pretty much have run of ship. For the ports we are going to our 10 year old will be able to go ashore providing we book excursions through RCL. If we just want to get off and roam ourselves the kids club will be available. I had heard that Cococay wasn't available to those under 12 but that's not true. There are no restrictions on Cococay. The ship restrictions for unvaccinated are mostly for adults, no bars, casino...etc. We will have restrictions as to which evening dinning room we can be seated at. They have 3 main dinning rooms on Allure so there really isn't an issue here.
Thanks for all the above responses. Hope this helps someone else. I thought I would have to cancel my Oct cruise so we could 'all enjoy' what Allure has to offer but now we look forward to getting back on the ship. Chow!
