Just returned from a week trip at Disney/universal. I did not want to go due to Covid risk but wife insisted. Turns out she was right as the trip was amazing. If you have kids whose focus is rides then this is literally a once in a lifetime experience. As someone who hates lines/crowded places like crowded amusement parks or large cruise ships(did
royal caribbean once and never again. I'll stick with Oceania) I would gladly pay twice or three times as much for the VIP like experience.
Magic Kingdom: Get there 30 min prior to opening and did snow white minecart twice with no wait. Rest of the day were mostly short/no wait. Kids did space mountain about 5 times in a row all walk on. Longest we had to wait was thunder mountain 25min.
Animal Kingdom: FOP and Expedition everest walk on = amazing day.
Skipped Epcot.
HS: As other said it's the most crowded park but still manageable. Got there early at 9:20am and was surprised all rides were already operating. We love toy story mania and being a walk on ride we did it 3 times in a row.
Overall points: 1) With the closed shows and short lines you really don't need multiple days at a park. 2) Even with the daily afternoon storms its easy to finish the park and ride multiple times at a leisurely pace. 3) We are relatively young and fit and statistically low risk if we had contracted the virus. Lets not kid ourselves, even with all the precautions there are plenty of crowded places/touching shared objects(3d glasses, interactive rides, etc), me personally would stay away if I was a high risk Covid group(tho I was surprised to see plenty of senior people there).
