How old are your kids? My kids are still young and really appreciated the long mid-day break in the cabana because their little legs were so tired. It is a lot of stairs. Your mind says ride, ride, ride, but your legs say tired, tired, tired.
I think being able to tap into ride lines in the cabana instead of heading to the ride itself to get a return time would be nice too, if the park has waits. We were there in early June and there were no virtual lines because the rides were all walk on. I do wonder how much more crowded it's gotten and if they've gone to virtual lines yet everyday or just on the weekends when they seem to be reaching capacity.
I think that if the kids are young enough that you have to be with them on the rides, you will appreciate the cabana for everyone to rest. I think that if your kids are old enough to hit the rides alone, YOU will be the one that appreciates the cabana. Just my opinion. We did the cabana on very low crowd days where we could have easily found shaded seating but we still really enjoyed the cabana, but we need quiet spots in situations like VB due to anxiety issues. It helps everyone decompress. It's a nice thing to have, but only you know what suits your family the best.
