If you have good budget, this is the option to choose without question. Here the party is simply to have the best of the best, the crème de la crème. The yacht would be the largest (100 feet Azimut, Azimut 85, Sessa 68 ...), the food the best (super ceviche, grilled seafood and meats outdoors, many couches ...), super service, best drink, the better accommodation and better transport. The best recommendation for this party theme is this combo:
Yacht Azimut 100 feet, because you already have two waverunners (no need to rent out), is the yacht with more rooms (comfort and privacy for Express lovebirds, always a room available), has gas grill and outdoor chef in his crew (more options for the event of "eat"), and something no one else has, outdoor jacuzzi.
Food: Kukulkan ceviche or grilled seafood and meat, because you yacht has gas grill on the third floor outdoors. The kukulkan ceviche is a leading cilantro, ginger, mango, cucumber, onion, horseradish, lemon, olive oil, fish xcochim, shrimp, lobster and queen conch.
Lodgment: Casa Enzo in Playa del Carmen, it is the most luxurious of which are mere dens area, 30 steps from the beach, in addition to chef, puncture, guard and several maids. It has two terraces for pre drink. The roof top terrace has jacuzzi / pool, large table and grill.
Transportation: Hummer limo, that will fit up to 12 people and is a hummer, better than the expedition, which is not bad either, for 14 pax. If more is the limoatobus, up to 30 people.
Price: the price of this event varies depending on the services, but good good leaves you approximately 12,000 USD
