Since you are at the villas, your are closer to the bus stop. If you wanted to, there is a bus from WL to FW, the stop for HDDR is the stop right after WL and the walk from the bus stop in FW to HDDR is the same(maybe a tad shorter) than the walk from the boat to HDDR.
The boat is a much prettier trip, the bus is faster especially on the trip home.
Before 3pm the boat runs clockwise(WL>CR>FW>WL) after 3pm they reverse and go counterclockwise(WL>FW>CR>WL).
