I forgot to mention....Cars Land is one of the best lands in all of the DL resort. It really feels like you are literally IN the movie. It's really awesome. Every evening at sunset, they have a cool little ceremony where they play "Sh-boom" and turn on all of the neon lights...just like in the movie.
I know that you haven't asked about this, but I would highly recommend for your parents to get their own hotel room.

Everyone will probably have a better time if certain people have their own room with a door that shuts. Even if you & your extended family get along like the Cleavers on "Leave It To Beaver," a theme park vacation can be trying for everyone at times. Having your own space where you can have some "down time" from the rest of the crew can really help a LOT.
The on-site hotels generally can only sleep up to 5 people in 1 room.
Off site hotels? You have more options. Here are some questions you will need to consider:
- is free breakfast a must have? If not, most of the off site hotels/motels do have small refrigerators & small coffee makers in the room. Some also have a small microwave.
- What kind of pool do you want? If you want a big resort pool with water slides & the whole 9 yards, then the on site hotels are the best options for that. A brand new Marriott Courtyard JUST opened on Harbor Blvd (http://www.marriott.com/hotels/travel/snadt-courtyard-anaheim-theme-park-entrance/) that has a water park. It has many sleeping options for larger families, but price-wise, isn't too much less expensive than the on-site PPH.
- Many people on the DISboards have stayed at and love Hojo's Anaheim. In the last 2 years, their prices have gone up a lot. Last week, I was looking at that motel for a room for 4 in early June 2016 and it's $189/night for 2 double beds even with a AAA discount. Hojo's is known for very good customer service and they don't charge for parking. They have a great splash pad/water play area for kids. Your 7 yr old would probably love that!
- Candy Cane Inn is regularly voted every year as the best motel in Anaheim. They have a good reputation for good customer service. They don't charge for parking either, I think. And room rate includes free breakfast. Within walking distance but they also have a dedicated shuttle (might help for your parents or anybody else with tired legs and you don't want to trek back at the end of a long day).
- Best Western Park Place Inn - <5 min walk to the esplanade. But pool isn't much more than a cement rectangle in the ground. It has a hot tub, too. Free breakfast. They, like many other motels along Harbor Blvd, charge for parking. Their "minisuites" usually can sleep up to 5 - if you get the room with 2 queens and a pull out sofa bed. I just booked a room here for next June for $129/night.
- Tropicana Inn - has room deals where you get a certain % off if you stay at least 5 nights. This place gets good reviews, too, and is right next door to BWPPI. This motel has a 2-room kitchen suite that can sleep up to 8. It also has "family suites" that sleep up to 6. Has a pool No free breakfast.
- Camelot Inn - also on Harbor Blvd. A sister property to the Tropicana Inn. Has a 1-BR family suite that can sleep up to 6. Has a pool. No free breakfast.
- Desert Inn & Suites - has a LOT of options for large families. Some of their configurations can sleep up to 8-10! Indoor pool. Free breakfast.
I'm skipping over a lot of other options. Google Maps will give you a good idea of how close or far away various places are. Our family has stayed at the Best Western Plus Pavilions on Katella and we really liked it. The room was very clean, free parking, free grab & go breakfast items, and the pool was very nice.
for our next visit in early October, we're staying a couple of doors down at the Best Western Stovall's. They have a larger free breakfast, 2 pools instead of 1, and they charge about $10/day for parking.
For both BW + Pavilions and BW Stovalls, we walk up Disneyland Drive and then go into the Grand Californian Hotel to get to DTD & the bag check at the Esplanade. More convenient & faster than taking ART. For us, it felt like about the same walk as it was from the DLH through DTD to the Esplanade (about 10 minutes).
If either of your parents are mobility-impaired and need a scooter, Deckert Medical in Anaheim rents scooters and they will deliver it to your hotel. Otherwise, you'd have to
walk to the park entrance, rent a scooter directly at DL/DCA, turn it in at the end of the day, and
walk back to your hotel.
If your 7-yr-old has the sort of autism disability such that being contained in a safe space is very helpful for you, you can rent strollers from Anaheim City Stroller and they will deliver it to your hotel and pick it up at the end of your stay. I have rented from them before and the strollers are GREAT. The strollers are VERY clean and they have stroller options that can accomodate heavier children (i.e., up to 100 lb).
