i paid very little attention to that. I wanna say most of the HP rides in both lands are indoors. I don't do roller coaster or thrill rides so have no clue on those at all. many are under cover if not exactly indoors. (Minions, Simpsons, IIRC) are you staying on site? many of the on site hotels come with their front of the line access included in the price, which can be a big help.
one thing I DID notice that all the ride vehicles are zero entry! no steps in or out! it was awesome as my knees and hips are the major offenders of my body and not having to rely on mr jvb to haul my overweight tuckus out of a ride saved his back.
