OMG! I can't believe you are thinking of switching! I am obviously biased, but I think I'm only upset really that there will be one less Aventura bride...especially when there are so few of us to begin with...and I won't be able to plan based on your wedding I had literally been counting down the days!
But, really none of that matters. If you want to switch, then SWITCH. It's your wedding and you need to be happy about the place you choose. I looked at Excellence and it really is beautiful. I think the only thing that would keep me from switching is the price...
Good luck, and keep me in the loop!
