Congratulations and happy planning! I'm planning on using Mandalay Bay but doing an in-suite wedding an reception. Their wedding coordinator has been very helpful and has been very reassuring. I haven't finalized anything yet, but she says that she can put it together in about a month. Vegas is so fun and is the perfect place to combine fun, whimsy, and a wedding. Good luck to you and let me know if I can answer any questions on the Mandalay Bay.
