There really are no high end places to stay close to Disneyland. I don't understand it, but since I've been going there for many years, I can tell you the choices have drastically improved over the years. It used to be all small motels with just the one Disneyland Hotel, the Sheraton and I think one other high rise, but I can't remember what it was. I would expect a full service higher end hotel at this point, but there's just nothing like that at this point. Still, it's been a steady improvement over the decades.
As far as what I'd like to see added, I'm not even sure. The reality is that I am out of the room and busy the entire time when I am staying in that area and I wouldn't get much use out of any services.
Because we are not Orlando and not anything like DW. This is a very locked in area and hard to find space. There are enough for those that come here, for the $80 a night to $800 a night. Now there will be an even more expensive hotel being built on property.
