Besides the obvious refurbishments, the whole area could probably benefit from some rethinking. Right now, most of the resort infrastructure is a 1992 leftover that has seen minor refurbishments and adjustments over the years, but overall things have deteriorated.
The security tents, for example, have been there for almost ten years now and aren't going anywhere. They've changed the geography of the entrances and exits, although they still accomplish this with temporary barricades. Isn't it time to build them a permanent structure? Then there's the parking lot facilities and shabby moving walkways with their thousands of yards of light bulbs that they clearly have no intention of ever changing... And that dated arch at the entrance that just says "Disneyland" that has somehow survived through 1,353 logo and name changes. And while they are deserving of a thread of their own, the hotels themselves aren't any less stuck in the past. (I mean, the era of air conditioning and flat screen TVs hasn't yet begun here...)
The nostalgic in me says "keep everything the way it was," but it's probably time for a few fresh ideas.
