Hojo would be great if you are okay with a little bit longer walk or will take the ART shuttle. It's about as far as walking to Paradise Pier but it just seems longer to me going down Harbor!!!
We stay offsite a few times a year and we don't really have a problem with it at all. Of course I love onsite, but I couldn't go as often if we only did that! Also even though my kids are 5, 3 and 10 months, we don't spend very much time in the room at all so that will make a difference for you. I like the Desert Inn and the Carousel also. Most of the rooms are the same between there and Hojo to me, but the grounds are the difference.
Have fun, we will be there the 22-24 going to MHT on the 22nd! See you there!
