The first time we stayed at the Hojo my kids were 9 and 7. The walk was fine. I mean at night it seemed long but the larger rooms made up for it! We took a break every day of our five night stay.
As you can see by my sig, we are staying at the BWPPI this time, because of the location. Its just for two nights (and one of those nights for a late arrival) before we head to the DLH so I am fine with that. I love the location, the rooms are nice, we like the mini suites and the free breakfast is convenient. All that said, if I was going to do a total offsite stay, I'd pick Hojo. The pool area at BWPPI is so lackluster whereas the Hojo has the new pirate pool plus the quiet pool. And the grounds at Hojo are lovely. BWPPI grounds are tub of flowers and a big parking lot that is crammed with cars!
So for me, if I am going to stay more than a night or two, I'd pick Hojo. It does stink to walk by four or five motels that are closer but again, the large sized rooms, grounds, and pool areas make up for it. If all you want to do is sleep and shower, close is better. But if you want to spend much time at the hotel in or out of the room, Hojo is better than any of the others in my book.
Have a great trip!
Oh, I'll also add that I have a little trick I used to do for my kids when they were younger and had long walks at WDW or DL back to our resort or to the bus stops after a long day. I'd give them a piece of gum! They don't get much gum at all, so I'd whip out that piece of bubble gum and they'd be happily chewing and trying to blow bubbles and forget how tired they were!
