After two days in the parks with EPs, we will be done by 7 PM on day 2, I am pretty sure. We should be able to do a lot of damage the way we tour
We might have reserved seats on the Mummy and DM by the time we are done. Knowing my kids, those two will be riden many, many times. Which is why an early shut down on day 1 is something I really want to avoid. Even if the kids are done by 7 PM, I can stay and go back to the resort later since we will be onsite. Day 2, we all have to leave at the same time because we will be staying at the timeshare that night.
(strange random thought, I just realized I am paying more for 1 night at RPR or HRH than for an entire week in the timeshare, but it very much worth it)
