I actually called back a bit later, trying calling the hotel directly but getting transferred to the same reservations line that I had originally called. I hoped not to get connected to the same person I spoke with the first time, and luckily did not. We actually had a split stay booked, but I didn't even get around to asking about the second hotel on that first call. When I called this time, though, the agent said we were lucky, that there seemed to be plenty of availability (to say I was shocked to hear this might be an understatement), and was able to secure roll in showers for both hotels with no problem and in the room categories I had booked originally. I didn't indicate the accessibility needs when I initially made the reservations because I couldn't figure out how to do it for just one room (since I made both sets of reservations at the same time) and I didn't want to tie up two sets of accessible rooms by accident. I admit my computer literacy isn't tops. Anyway, this second agent was able to confirm that my parents would be on the first floor and that my family (my husband and I and our kids) would be in connecting suites so we can easily assist if they need help for the first hotel, and that we will be nearby, but connecting requested for the second. Our room numbers are in the reservations for the first hotel. I was astonished. She even provided so much helpful additional information over the phone about accessibility. It was such a night and day experience. Very glad we are going on this trip, and renewing APs was a good call. I had talked my parents into APs and they were also excited about going, so I am super happy that this second agent picked up the line. I will write a note to Universal to let them know how extremely grateful we all are for her guidance. I figured there is no need to even mention the first call. I hope this might helpful someone else, but I know availability can fluctuate.
