I see the promotions for the 5-nights/6-days but I've read that you can get the regular DDP if you stay at least 3-nights at a moderate hotel. Is this true? If so, how am I supposed to book this online? Do I book the reservation without a DDP and they will automatically include this once I arrive? Or am I supposed to pick a dining plan and they adjust the price afterwards to reflect the deal? I planned on staying August 19-22 at the Carribean Beach Resort.
