So sad about the Wave - was our favorite breakfast place - the buffet was relatively low key, but classy. Am sure, like other buffets, it will not return. All our favorite places (restaurants, venues, rides, street shows, etc.) have been discontinued, or changed beyond recognition, so we are getting farther and farther away from a return to Disney. They've squeezed the daily park admission hours so small so they can add other big ticket moneymakers into a normal day, all the while increasing ticket costs, that it is totally disgusting to us.
Have gone for 50 years and until the last 10 years was such a fun place to be, but a lot of the changes (cost cutting, or better money makers for them) have dimmed our enjoyment almost completely. The restaurants used to be such an adventure for us until they were dumbed down and totally mostly just meh now, even before Covid. So many other destinations we are beginning to enjoy more now. Great memories for us and our children will live on though.
