I’ve been to WDW so many times, and all my memories are blurred, but one that is a clear stand-out incredible memory is going to AK lodge for dinner with friends back before we had little kids to schlep around. Great choice! You will love all aspects of it!
If you are going all the way to AKL just for dinner I would consider Sanaa over Boma. Then you can just sit and relax and maybe see some animals depending on your table.
I try to limit our buffet meals though. I agree that Boma sounds like a better choice than CP.
