How is this place for 2 girls (35-40 yrs old) to get away for a week of fun? Is it loaded with couples or are there both single guys and girls? What is a must do while we are there? We live in Maine so the beach in Jan is gonna be great. Anything special we need to bring? I always tend to over pack are there dress codes? We leave Jan 17th for the week and can't wait. This wad BBG when we book the reservation thru RCI. Is it an advantage or disadvantage being an RCI member? Any tips would be great.
