Wow! This has been so helpful. We really appreciate everyone's honest opinions and we've loved reading the variety of responses.
A few more details: we will be driving, so no flights to worry about, and no children. We try to make it once a year, so the idea of adding this unique experience to our list of trips is very intriguing. We're booked at Caribbean Beach for the Skyliner, and we'd use our car for MK and AK. Our favorite things at WDW are rides, fireworks, food, and soaking in the ambience. We don't care much about parades or waiting in line for characters, so the cavalcades seem like upgrades of those experiences to us.
Today, we're leaning towards going. Yesterday, we were leaning towards rescheduling. I think we'll keep going back and forth until we can't wait anymore, so we continue to appreciate any new perspectives. Keep them coming! Thanks for the tip to scour the trip report forum as well.
Hubby and I were there in mid December. We stayed off-site, so that's a little different, but in other ways we are very similar to you. It was just us, and we drove there and used our car to go to all the parks, but we did take a break from Epcot for an afternoon Skyliner tour (which we enjoyed very much, we adore the Skyliner).
We have been frequent visitors for many years, but this was our first trip back since the closures. Like you, we don't care much about parades or character meetings, and we like all the things you do.
It was a mixed bag of a trip for sure. Getting the negatives out of the way first, the hardest thing to swallow for us was just how many things are not running. We missed the shows very much, especially Festival of the Lion King, and having some of the restaurants not be open sucked too. Wearing masks all day was not that big of a deal, but it was harder to find water than we expected, and we tended to get dehydrated because of that. We typically get lots of free cups of ice water from the counter service places, and that was much more challenging this time with the emphasis on mobile ordering, especially in the MK. To be fair, we were there on the first day and getting our bearings, so maybe we could have done better there. We did better at the other parks.
The cavalcades were a fun surprise whenever we saw them. I'd be happy if they keep those in the future. However, be careful, because crowds do sometimes form around them.
Lines were not that big of a deal, and honestly it was kind of fun doing it like we used to do it back in the day before FP. Social distancing was pretty good in the lines. We had one exception with a party of 4 who kept getting too close to us, so I invited them to pass us. They gave us a confused look, and I said, "no really, please, just go in front of us" kind of firmly, and they did, although I don't think they understood why.
Overall, I think you're good candidates for going during this time. It's not your first trip and it likely won't be your last, so just go have some fun. Just manage your expectations and appreciate it for the unique experience it will be. For us, we made our decision to go based on how much we wanted some kind of a vacation experience after our very challenging year, and we're not sorry we went.
