Not sure where to post this, so in Misc. it goes!

For anyone who has shot at Calamigos Ranch in Malibu, what's the lighting like there at night. I'm looking into shooting a late October wedding there, at "the cottage" by the tree with the twinkle lights, and I suspect the sun will have gone down once the ceremony starts. I assume some flash will need to be used, but didn't know if there was any additional ambient light on scene. Client was asking about hiring a vendor to bring in additional lights, but I first wanted to ask if anyone had any night time shoots up there and how things went (flash, additional lighting).

Thanks
Steve
