Wow! Congrats - I am sure it will be awesome.
MrsMac's brother is my DH. The wedding just over 3 years ago (the weekend I found out I was pg with DD... awwwww...) was at the Warwick, and it was very professional and very nice, even though the weather wasn't kind to them. He got some fabulous shots (and as his assistant for the day, so did I - one of mine even made it into their album, LOL!). The staff were wonderful and the food was nice from memory. I am not sure whether this couple got special treatment though - her parents are nationals and friends with the president
Sounds like you've been given a great lead though on a place that's more cost effective. I imagine the wedding we attended would've cost a fair bit.
GL - I am sure you will have a glorious wedding day!
