Funny enough, I find park hopping the reason that
Genie+ IS worth it, as you can usually get more big rides in when you’re not limited to one park.
My rule of thumb is never book something more than an hour out (unless you have a break or meal obviously), and your first reservation of the day should be used in the first hour of park opening. Sometimes this means doing things a bit “out of order” in that I ride a middle tier attraction with an earlier return time and then bank on picking up a
lightning lane for the bigger ticket ride later in the day.
Unless the return time is immediate, I NEVER settle for the time shown on the top board when I first look. I ALWAYS refresh the tip board constantly for a better time. Lots of blog posts and videos out there on refreshing the tip board. I can get a return time within an hour for just about any ride within a couple minutes of refreshing, up until the last hour or two before park close. A few attractions may take 5-10 minutes of refreshing but usually that’s later in the day when pickings are slimmer, I’ve never really been fully shut out. Some people don’t want to be on their phone so much but 3-5 minutes of refreshing per ride sure beats 60+ minutes in line per ride for me any day.
It will be harder to refresh for HS rides in the later day than MK rides but both are completely possible and will get you “more for your money” imo. I’d venture to guess at least 4/5 people using genie+ don’t even know they can refresh the tip board and just take the first time they’re presented with, which is why Disney says only 2-3 rides a day is normal.
