Hi
To clarify
"... Parking is available in the underground garage, entrance BEFORE the Maho roundabout...."

"BEFORE" refers to coming from the airport
If leaving Maho, the entrance is towards the airport immediatley after the roundabout [left turn]

First time looking for that gargage entrance drove past it twice before I figured it out!

Always felt comfortable using that parking lot vs Maho across from the casino.
I have always accessed it thru La Terrace [maybe not supposed to?] either elevator or walked down the stairs
