Just returned from BLT, we were given room 7912, a 1-bedroom lockoff HC room on the 9th floor. No one in our party required a HC room.
We were confirmed for a bay view, and waitlisted for a mk view. We were able to see MK and the bay -- it was great watching the fireworks from the balcony. Still not sure if this was considered an MK view or not, but it did not "cost" any more points than the bay view we booked.
Please excuse my terminology --- The bathroom in the master was fully accessible. No thresholds, low handle on the door, roll under sink, rails near toilet, lots of space next to toilet, large shower with no threshold (ds10 did cause a little flood!), pull up seat in the shower, lots of rails in the shower and a second handheld shower head.
Curious though there was no soap holder at all in the shower. Is that typical in a HC room?
The second bathroom, while it had no threshold is small - tiny tub and no rails. Other than the threshold I believe this is the standard bathroom.
Hope this helps.
