We stayed at the Grand July 2011 and were told no bed rails were available. Not sure if they were out or just don't have them. We wound up pushing the queen closest to the door up against the wall.
Not take off topic, or be particularly preachy, but I would be VERY cautious about doing this. While a sleeping child rolling a few feet off the bed onto a carpeted floor isn't ideal, it's also unlikely to result in serious injury. More likely your worst case scenario is a bruise and lack of sleep as you soothe them back down from a less than pleasant wake-up surprise. But getting stuck in between the wall and the bed could be fatal, as a deeply sleeping child (and toddlers can sleep very deeply) could easily suffocate between the wall and mattress if wedged in. Not worth the risk, in my opinion. (And many types of bed rails themselves have been taken off the market, for the same reason.)
If you're really worried, put a few pillows down next to the bed, or fold up the comforter or whatever, to create a soft(er) potential landing spot. (Or, heck, request one of those sleeping bags the Grand says they offer and use it as your cushion. Or even stuff it with pillows for extra squishiness.)
In general, and I know there are exceptions, but parents tend to worry a lot more about kids falling out of bed, than falling actually occurs. And when it does happen, some kids even sleep through the experience, waking up on the floor in the morning. My son is, even at 5, an incredibly floppy sleeper. He thrashes and kicks and turns every which way but loose in his twin bed, but has never once fallen out, and he's been sleeping there solo and rail-free since he was 2-1/2. He basically strips his bed every night with all his movements and I've seen this kid stand up and do a 180 turn, and fall back onto his mattress ... All while asleep. Makes him a joy to sleep next to, let me tell you (and I know because he's been sick, and in our bed, the last three nights <ugh>), but he's never been hurt in any of his nightly gymnastics.
Obviously you need to do whatever you think best, but I just wanted to point that very real danger out, in case it's something that hadn't been considered.
I've also walked down to wonderland liquor (5 min walk for us but we walk brisk). Just exit the GCH to the left and take a right at Katella. It's across the street and down about 2 blocks. They had a huge selection of wine and great prices. Also sold food, tolietries, etc.
) We had a standard view room that faced out towards Disney Drive on the 5th Floor (5235). The room was in super good condition and very clean. The pictures on the DIS Grand California Hotel rooms show the older bedspreads. I guess I should have taken some pics...but, our bedding was much newer looking than the ones pictured. 
... any way it was a great room/view and we really enjoyed it.
