I had never done this before in all of my traveling... but when we got into our room it was ground level. It was park side, but you couldn't see anything. We were only staying one night for a spendy 40 points and thought what the heck we can ask... We called to see if anything else was available and they were very nice. They checked and there was another available studio...... a cast member met us and took our old keys and gave us the new ones. We were no longer ground floor but but didn't have view of the pier.. we had a view of the Grizzly playing area and a corner of the pool.
So it doesn't hurt to ask once you're there!
