Hi, Luverly, my favorite hotel is HoJo, which is closer than Menage. It's one block up from the park entrance. HoJo is a favorite on these boards because of their Entertainment book rate, which is $59-79 a night on certain dates. I just checked, and the Ent rate is available for every night of your stay. This is the best deal on Harbor. It's the nicest hotel available at that rate within walking distance! Here's the link with the dates and more info:
To get the Ent rate, you need to call the hotel directly at (714) 776-6120, and ask for IN HOUSE reservations (not the national reservation line; they can't help you with the Ent rate). Call between 9-5 Mon-Fri, pacific time. Jennifer or Lorealle will help you. You don't need an Entertainment book to book the rooms; you'll just need to show the card when you check in. If you don't have a book or a card, you can order it online-- in fact, the cards are available by themselves on e-bay for just a few bucks.
Menage is nice from what I've heard, but it's too far to hike. I mean, it's do-able, but you will already be tired at the end of the day. HoJo is a 7 minute walk, and even it looks SOOOOO far down the street at the end of the night! Menage is a good half-mile or more farther.
Check around a little on the boards, here, a few pages back; there's been some reviews and pictures of HoJo that people have posted lately.
Hope that helps!
