You may have heard that Kate Middleton was spotted leaving Westminster Abbey this week so the newspapers are speculating that Westminster Abbey will be the location of her wedding ceremony.
Every bride should visit ceremony and reception venues before signing a contract. The exception for this of course if you're having a destination wedding, in which case I suggest hiring a wedding planner who you trust to vet locations for you.
Bring along a list of questions to ask the location manager and don't be afraid to ask any and everything that pops into your head. Better to know the answer before paying a (non-refundable) deposit and signing a contract.
Some brides will look at several locations and narrow the list down to their top 3-5 and then bring their groom and parents to take a look and check out the space. You may also want to do this with several vendors, especially ones your fiance isn't that concerned with like the florist.
I dragged Dave to 10 locations in one weekend and I think we saw a dozen florists and I could tell that after the 3rd or 4th appointment he really didn't care and just wanted to go home. It would have been better for me to vet the locations and vendors and only take him to my top 3 picks where I would have had his complete attention and interest.
