Hacienda Cocina is a great venue and I can give you a lot of info! The contact person there, Susana, was really great. Basically there are 3 different areas to have your reception in:
1) The restaurant. This requires a buy-out with a minimum consumption of $20,000k. This obviously doesn't make sense unless you have at least 100 guests. This is way out of our budget but there was a wedding the day we went that was doing this and it looked awesome. If you do the buyout you get to have this awesome little cocktail area too and this awesome bar area/palapa type thing for your dance floor.
2) The beach front area. This is a small area that is designed to hold about 45 ppl but she said it can go up to 70ppl. The minimum consumption is something like $2500 plus a $250 site fee (these numbers are ballpark of what I remember her saying--not exact). This area would be awesome bc it's directly on the beach.
3) A terraced area in the back. This area overlooks the pool and holds a lot more people. The price is something like $5,000 minimum consumption with a $600 site fee. Another great area.
The ceremony would be held on the beach and there is a grassy area between the beach and pool where you do the cocktail hour. The only thing I don't like about this venue is that the beach area is close to the hustle and bustle of Medano Beach. It's not close enough that you can hear the noise or anything but in pictures it would be nearly impossible to avoid having other big hotels and stuff in the background. You could shoot towards the ocean but at this beach there are a line of buoys in the water that I think make wedding shots not look as nice as if you had a clean ocean in the back. I realize many people won't care at all about this but for whatever reason, it's a deal breaker for me. If you aren't as picky about this sort of thing I think this is a trily fabulous venue. We also aren't going with Hacienda Cocina because you have to bring in all the rentals (chairs, linens, etc) and we are trying to avoid doing too much of that.
Oh another great thing is that Susana said that at the end of the night, she is willing to print out 2 receipts: one for how any drinks were actually consumed and one for the open bar price and she will charge you whichever is less. That is a great perk! That way if people don't drink as much as you anticipate you can save money.
