Disney Proposal

Well I finally did it!!! I flew us down to Disney World for the day. She worked there for a year and is absolutely obsessed, so I told her I had to use my requesnt flyer miles before the end of the month or they would expire, and went down Saturday night. We spend all of Sunday, and then I had a private boat ride for the Magic Kingdoms fireworks show. I asked the Captain to take a picture of us, and then after that asked him to take one more, and proposed. She absolutely loves the ring, and couldnt be happier about the design. It is however a little bit big. Is getting it resized something that I can just have done local, or is it a really big process?
