we've been down several times now since the reopening and we always have a great time. the biggest thing to get used to is you have to properly wear a mask everywhere that's not your room/car, in a pool, at a "relaxation station", or while actively eating (while both stationary and distanced). if it's summertime, carry extra masks with you so you can swap them out as the day goes on. And bring your patience pants, as there are no fast passes at the moment so you'll need to stand in the lines old-school style. the lines will seem super long due to the distancing requirements, but the wait times seem fairly accurate so that 5 mile long line for Tower of Terror really is only 45 minutes if that's what it says. read up on tips for getting your Rise of the Resistance virtual line passes, as they go in seconds and you want to be ready at exactly 7am. most every counter service restaurant uses mobile ordering which is a fantastic upgrade. food booths still have regular lines.
but honestly, August is so far away that they might loosen the rules by then (now that the vaccine rollout is in full swing).
