Where to Honeymoon in Mexico?

[FortFun]

I am getting married this summer and my fiancee and I would like to honeymoon in Mexico. We have never been to Mexico so we are at a loss on where to look. I have been looking at Puerto Vallarta some. Are there other places I should look, or any resorts specifically?

We would like something nice(obviously) and all inclusive. Any help is greatly appreciated.
