We had a fantastic wedding at Deer Park Villa, and at the end of the day, are happy we chose the venue, which is really quite beautiful. That being said, the venue was at times quite frustrating to deal with leading up to our wedding, which for us was compounded because we were planning our wedding from across the country.
The biggest issue was that we felt there wasn't complete transparency and forthrightness from Deer Park when we booked the venue. Apparently when you book Deer Park, you don't buy out the full site -- that we learned after the fact was an option, for more money, but no one mentioned this to us. At the time we booked Deer Park, which was about 10 months before our wedding, there was no restaurant or bar on site, and no one mentioned anything opening, so we (perhaps mistakenly) assumed the space was ours. It wasn't until our caterer had asked if we did a buyout of the site that we learned about all this, which frankly is quite frustrating. Then we learned that Deer Park planned to open (and now operates) a public bar out of the front of the building. We weren't told that from the beginning and didn't know that our rental excluded that part of the building, and (more problematically) the public would be sharing the building (and bathrooms) with us.
The bar has pretty sporadic hours and fortunately it ended up being closed during our wedding, but it's still quite frustrating that they didn't explain that was a possibility to us when we booked, and it led to some headaches. So just make sure if you book Deer Park Villa, you are very clear on what exactly you are reserving/what your rental fee covers.
Further, there was a lot of confusion about outside music. When we booked the venue, they pointed out the ability to have music and dancing outside into the evening. But our contract explicitly required all outside amplified sound to end by 9 pm. And then, a few days out from our wedding, they told our DJ that outside music had to end by 8:30. We ended up making it work (music can continue inside the building and there's a dance floor in there - it's just not as picturesque as the outside), but it would have helped with our figuring out our day of schedule if the music issue had been clear from the beginning.
The responsiveness of folks at the venue was also sometimes pretty spotty. Once people responded, they were helpful (in particular Miguel, who heads the bar, was very helpful, particularly with personalizing our bar), but you had to often nag folks. Also, a small quibble - at least for our wedding, Deer Park did not have a to-scale map of its space, so trying to lay out tables and figure out how to use the space was challenging. Our coordinator created a to-scale map on her own when she did a different wedding at the venue.
All that being said, on the actual day, the staff at Deer Park was very helpful and on point, and we had a fantastic, lovely wedding. So basically, just be extremely clear with them from the beginning, get things written down, and if you're a bride or groom who wants super prompt responses, Deer Park might not be the venue for you. But if you can let some stuff slide, at the end of the day you should have a great event (the venue really is incredibly beautiful).
