Everything was nice, but I did have to inconvenience the staff.
I know by now that I must be awake, in the room, to recharge cell and laptop (electrical system shuts off if I remove key from the slot). While checking in, I asked for 2 keyes, so that when I left the room with 1 key, the other would keep the electrical system on. Staff was unable to supply 2d key, but told me they would let me in.
Later, I left hotel for 1/2 hr, leaving key in slot. Staff needed to physically go to the room with master key to let me in. I felt sorry for them.
