Our resort does more than one wedding a day, with space available for every hour. But, they have 4+ locations for weddings, multiple reception options, etc. So even though there is the possibility of having 6 weddings in a day they currently don't have that many.
I look at it like weddings are their business. I have read every review I can find and not a single bride has complained about anything going wrong, details being forgotten, running late for their wedding, etc. Because this is a highly rated resort specializing in "romance" they have a pretty good system worked out.
I think if you are comfortable and have good communication with your planner, everything will be fine. I was worried about this so I discussed it with my planner. THere is 1 vow renewal at 11 am, a wedding for the couple only at 1pm and a wedding at6 on the opposite side of the resort that day. My wedding is at 4.
I'm also bringing my own photog/videographer and doing my own hair and make-up.
I'm really not worried about it and still look at it like it's "My Special Day" because it will be!
