My husband and I were married at the Phoenix (sunset ceremony) in March 2005. It will be the most beautiful, stress-free, wonderful wedding you've ever been to!
We were scheduled to start at 6:00, but I think we didn't actually get started until about 6:15. Either way, it's a great time to do it. I think the sun is finished setting around 7:00 or so. Are you working with Indira from Aruba Fairy Tales? That's who did ours, and she really had a good grasp on the timing - she is SO on top of things!
Let me know if you have any other questions, want pictures, etc. Congratulations again, and blessings to both of you!
