I used to always get PH, but for my current family, we are happy with one park per day (me, DH, DS- 12, 10, 2, and usually my mom, 64). We take a pm hotel break and even with just 1 park, we walk SO MUCH. I couldn't imagine hopping. I suppose if we were heading to the opposite park after our break it would be the same amount of walking.
If I didn't have a small child or my DH and mom were both more mobile, I might consider it. But the $ adds up for 6 of us. I'd rather put my money in MP.
If you go without, it will be totally fine!
