I know it's expensive -- but get someone to shoot a video of your wedding
#1 -- anyone who can't come -- you can show them the video later on
#2 - you yourselves will be in kind of a trance, that way you can watch the video and fully enjoy (later) what you didn't see or realize at the time
pictures are great, but a video puts you *right there* especially if something particularly special happens
cake_ I second the idea of having several different flavors -- more in the fillings than in the cake itself (I'd have lemon as well as the suggested strawberry)-- BUT there may be people there who are on "sugar restriction" -- many are these days and they might not advertise it -- so I'd suggest also an angel food cake with fruit instead of frosting, for those who "eat light" ... or as was also suggested, shortcake ...
and have sugar-substitute for coffee or tea; or use Crystal Light mix instead of (or as well as) sugary lemonade or punch
the less you "fuss", the more fun people seem to have
one song that is lovely, perhaps not your style, is "I Honestly Love You"
another is "(Your Love's Put Me on) The Top of the World"
