"Rope dropping" seems a bit easier since COVID because all of the parks tend to open about 30 minutes earlier than the posted time for everyone (no more scanning magic bands to confirm you're at a Disney Resort and the ENTIRE parks are open, not just designated sections). I've also been super impressed with the way they've been able to quickly get everyone through the gates. On our last trip, the bus service was a bit confusing - I think a cast member told us that they only start running 30 minutes before park opening. I never tested the theory, but if that is true, a rideshare may be the best option if you are intent on being there at least 30 minutes before opening. Keep in mind, though, that a rideshare will drop you off at TTC for MK, so you'll end up taking either the monorail or a boat. At MK, everyone goes to Seven Dwarves, which leaves the rest of the park empty. At AK, the same can be said for Flight of Passage. So if you're content missing those rides, you can plow through a ton of rides in the span of 90 minutes.
