Just back from a weekend visit April 11/12 all all four parks, in case this helps.
First wrinkle, my daughter and son-in-law who were supposed to drive over from Tampa but ended up needing to quarantine and couldn't come. (They found out two days before, so completely last minute.) I changed their theme park dates to the fall when I am returning, but that left me completely alone all day Saturday, because my friend who has an Annual Pass was shut out of all park availability. She'd already managed to snag a reservation to join us on Sunday.
When I changed the ticket dates, it did not alter the three reservations in my
MDE for Studios that Saturday, so I went to Disney Springs after I arrived Friday and a CM was able to reassign one of those reservations to my friend! Very happy surprise! We spent the rest of the evening walking around Disney Springs waiting for our Gideon's return time. This was the longest thing we waited for all weekend, lol -- joined the virtual queue at 5:52, called back 9:18, inside 9:45. We watched the very last cake slice of the day disappear and we ended up buying the last April specialty cookie in the shop. I was surprised they still had some that late.
Saturday morning (9 opening) we arrived at the Studios parking gates at 8:10 with a few cars at every line. They started letting people in at 8:15, we were in the park by 8:45. She'd never managed to ride Slinky Dog so that was our goal, but it was down. We'd struck out at getting a Rise boarding group at 7:00 but managed it at 1:00 (I'd never ridden before). After we booked that, we took the Skyliner over to Epcot and spent a few hours taking in the Flower and Garden Festival (super hot, rains approaching) and then rode back to Studios for Rise, which was down when we arrived, so we grabbed a bite at Backlot (which is when it started raining). Rise was back up, rode that, then walked on Mickey and Minnie, then got in a 30 minute wait for Slinky Dog. It was a nail biter as the rains picked up and there was an announcement they might need to close, but we made it. Still had time to walk on both Toy Story Mania & Alien Saucer Swirl before close at 8, and enjoy the lights in Galaxy's edge before heading out of a pretty empty, beautiful in the rain park.
Sunday we parked at the MK lot, then took the resort monorail to GF to bus to AK for the morning, fully prepared for the incoming heavy rains (but not all the rides going down at once). Highly recommend packing a roll-able raincoat, waterproof backpack, and waterproof shoes.
By the time we could hop to MK, on the app it looked like almost everything had a star instead of a wait time. We bussed from AK to Wilderness Lodge, then bussed to MK from there. There was a mass exodus by this time and MK was emptying out. (2:30). But most of the rides were back up and running by then. We had a lovely time, walked on Haunted Mansion, Big Thunder, Pirates, and Ariel, about 15 minute waits for Space Mountain and Peter Pan. We stayed until 8:00 and enjoyed the sunset and all the lights coming on.
