How does this wedding sound. Do you think I'll be disappointed when its all said and done?

It seems that you have done a lot of thinking and research on this. Bottom line is, do whatever you and your fiance WANT to do. It is your wedding and do what will make you happy that works within your budget. Since you have some time before your wedding, many of your decisions may change before the date anyway. Also, you will always have some critical family member or friend that will have something negative to say about your wedding no matter what it looks like, so just remember that it is your wedding day and it should be a reflection of you and your fiance!! :o)
