Have you considered the Northern Sea of Cortez. We have a 110 foot, brand new vessel that explores the midriff islands at the Sea of Cortez.
Rocio Del Mar Liveaboard - eat, sleep & dive.... as far is liveaboards go this is very reasonably priced. You would fly into Phoenix Arizona so airfare would be very affordable. Your are picked up at the airport or a hotel near the airport depending when you arrive, by a shuttle, and it is a 3 1/2 hour drive to Puerto Penasco. That is where you would board the Rocio Del Mar.
This destination was described by Jacques Cousteau as the worlds aquarium. We have our first trip which is a dive and whale watching trip. March 20-27. It is at this time whale season. We also have trips going out all spring, summer and fall. Check out the website and give me a call.
