My wife and I got the Hyatt Place on a Priceline bid for a steal last year. I wasn't sure what to expect . . . I also read the reviews online stating that it's too far to walk. It's not. I'm not a very athletic individual. If you can walk around a theme park all day, you can make the walk to the park. It takes less time to walk there than to take the bus, because the bus stops at 5 million other hotels after the HP. You just walk up the road, past a few hotels, cross the main road that runs in front of the UO parking structure . . . you'll be to the right of them, right by the kennels. At that point, you're only slightly farther away than people in the parking garages. It's not that much more walking than it would be parking in the one that is farthest from the park entryway. Maybe an extra 5 minutes, if that. Don't sweat it!
The rooms were WAY better than expected. It was pretty fancy for us. We're DVC members now, and I must say that the HP rooms are way better than the ones in Disney's Beach Club Villas. It was a modern decor, and they have HUGE flat panel TVs in there. It's set up like a studio apartment, with a little kitchenette and all. no microwave, just a wet bar and a fridge. You'll dig it, unless you are a Ritz-Carlton frequent stayer.
Even then, it's a great place for the money and then some.
The free breakfast is a nice bonus. You can swipe an extra cup of milk and cereal to go & stick it in your fridge for a midnight snack. Nobody will care. And if you want to do Citywalk -- this is great -- no taxis required! You could easily walk back to the room intoxicated. It's a mild trek, but definitely doable. If you're on this forum, I assume you can handle a kamikaze park day, in which case you'll be fine.
Enjoy your trip!
