Just came back from Macau and my experience is the same as CO-PLAT, got the same paper and got the same upgrade (had to push a bit). Guests at the JW and Ritz can use the Grand Resort Deck (with lazy river, slides and other things) max 2 adults and 2 kids per room, all other guests will be charge MOP 150 per entry.
@Sharon - E+1 is enforced on adults only. Plats can take the breakfast from Urban kitchen (very nice restaurant) but only 2 heads per room. In the lounge there was 2 computers and printers. No Key access after lounge is closed. Stayed March 20, 2016.
