Stayed at CCI in July. Just got back from our first time at HOJO's this past weekend.
We'll be going back to the CCI for sure. Service is MUCH better, rooms are nicer, and the CCI is just more mom and pop style where you get the tangible sense that they are trying hard to please.
HOJO rooms are old and while not dirty, feel very...worn/lived in. The front desk doesn't seem to care about your stay one way or another (no late checkouts, you have to pay for the shuttle which is free and always on time from CCI, the staff at CCI was just more real/caring and went above and beyond when assisting us ((i.e. they gave us a free ride from CCI to
Disneyland Hotel so we could make our Goofy's Reservation on time; there was a very nice basket in our room upon check in, etc)) ). At HOJO I got the sense that we were just one of many and they seemed to really take guests for granted. Not that it was a bad experience at all (it was not). But just compared to CCI, the service was non-existent at HOJO.
All that said, the HOJO pool and gift shop can't be beat and if you have kids, those are perks that are hard to come by at CCI. The CCI pool is fine/nice enough, but it's nothing close to how cool the pirate themed pool area is at HOJO. But heck, we went for the parks and didn't spend much time in HOJOS anyway.
Room service sucks at both. At HOJOS you gotta go next door to Mimi's Cafe to get food which kind of sucks. My kids dig the idea of people bringing food to the room. And on top of that, Mimi's can get crowded often with 30+ min waits. CCI room service exists but it's bare bones. They try to dress it up and present it all nice (and they do) but the choices are still pretty limited.
So there's my ramble

All said: CCI all the way
Either way, enjoy your trip!
