I can answer for RI - yes, a elevator to upper floors

RI has two wings - an L shape. Wing "1" is on the street side, "2" is parallel to the Maho hotel next door
The RI web site has room plans for the 1 and 2 bed units

Room # info - the room tells you where the room is
Room 4104 means
4 - 4th floor
1 - street wing
04 - 4th from the elevator
