Oh yeah, I'm planning on doing that.
I remember at my sister's wedding I didn't have time to even say HI to all our family who was in from out of town - and I wasn't even the bride. So I want to make sure there is time for that at our wedding. My FH and I both have HUGE families, and family is very important to us, plus we have lots of friends who will be coming in - our guest list is almost 300 "must-invites". So, I'm hoping to have many little events throughout the weekend in addition to the "main event." Here's the schedule:
Friday night: Rehersal dinner w/ FH's family (they all live around here) and Bridal party/spouses. I figure most OOT guests (which is my whole family and all our other friends) probably won't get in until late Friday or even Saturday, so this is a good time to visit withhis fam (who I see every holiday anyway :-P)
Saturday Day: We have a really nice park here which offers $10 day passes for everything from mini-golf to a zoo. I plan on renting a pavillion and "advertising" that friends and family can stop by anytime and say hi to us, while they enjoy the parks amenities. We have a LOT of little cousins in the family who will need theentertaining. I may even have the hair dresser come there :-P My FH husband also plans on going golfing with his friends and my dad/brother, and if we can afford it I'd like to offer snacks & drinks at the pavillion.
Saturday Evening: Wedding & Reception
Saturday Night: After party with our HS/college friends and younger relatives. Plus possibly an "early" after party for my mom & her siblings (mom, as well, was running around at my sister's wedding).
Sunday morning: Farewell Breakfast for Bridal Party & my family. Hopefully they can stop by and get breakfastwith us and/or grab some snacks from the road. Since we only really see our family at weddings & funerals (and I'm the only cousin left to get married), I really want to snap a family portrait here too.
We're lucky that around here there are a few venues (B&Bs) that you can rent for the entire weekend, so I don't have to search out a location for each of these events. The farewell breakfast is even included in one of the packages
Well, those are my ideas

The wedding isn't until Summer '08 so I'm sure the game plan will change 1,000 times before then. I'd welcome everyone's input!
