I know this is last minute but my wife and I rented a house right on the beach in Sayulita, Mexico, from May 12 - 21, which is about 40 minutes drive north of Puerto Vallarta. We have a pool, too. May is peak wind season in the area, with 20-25 knots on average. We have two extra bedrooms vacant. The cost is $80 per night, per bedroom. There are a ton of kite spots in the area, all within about 12-15 miles. Sayulita is actually too protected for kiting, but if you surf, it's awesome.
Here is the house:
The best kite spot is in Bucerias, about 20 minutes away:

Destiladeras is also excellent:

Email ASAP if you are interested (firstname.lastname@example.org). It should be epic. There is a national kite event scheduled for that week, too, in Nuevo Vallarta. It's also a terrific place to learn to kite. Check with Raquel at Kite Vallarta (email@example.com) if you want to get lessons.
