-limited trash pick up, almost no options. Maybe someone else can give some input
-yes, generally plenty of room to anchor if you are comfortable anchoring. Can be a big swell if coming from the south.
-both crown bay and yacht haven grande are easy to pull in and out of. Coming from the east probably stop at yacht haven grande. Coming from west then probably stop at Crown Bay.
-water and Druif are generally very crowded. You might find a spot to anchor at honeymoon further out. Another close option is Lindbergh bay. Tons of room to anchor.

Have fun
