We are going in September as well with younger kids, and I expect it to be so hot that I would like to do a morning and an evening shift with the hot afternoons spent at the Hojo pool and eating lunch before a nap. I am not sure how much our grandkids will like the rides, so I plan to kind of let them choose what looks appealing and ignore the stuff they have no interest in. There are a lot of good shows, and we plan to watch Mickey and the Magical Map, the Frozen show at Fantasy Faire, Soundsational and the Pixar Play Parade, Aladdin, and any of the night time shows they will stay awake for. I think the most gentle of the rides to start out on are the fantasy land ones, Buzz Lightyear, Pooh, Toy Story, The Little Mermaid, and Monsters Inc. Once we see how they do on those, we'll try others. I also don't know if they'll be into meeting characters either, but I know they'll love running around Toontown while I take adorable pictures! Tom Sawyers Island might be fun, too, and I can't wait to explore the Redwood Creek Challenge Trail in DCA, both are areas where the kids can run free for a while after they've waited in too many hot lines.
I don't plan to stick to much of an itinerary, because I'm sure the kids would just blow it for us anyway. So it will be a slow paced relaxed trip with plenty of downtime so hopefully no one cries too much...
I plan on spoiling the kids and letting them each pick out a Mickey Ear Hat and special souvenir from Grandma and Grandpa. There are also lots of treats to enjoy, like frozen lemonade and Mickey ice cream sandwiches.
I am bringing my
Disneyland spray fan and Adventureland Bizzare straw fan, plus I bought some 'frog toggs' online (moisture absorbing towels that cool you through evaporation) so hopefully between those things, frequent air conditioned breaks, and skipping the hottest part of the day we will be able to withstand the end of summer heat. We are from WA state and used to cooler climate. I expect the kids and adults to get cranky if we are all roasting and sweaty...
Have fun planning!
