We invited over 300 ppl (about a 100 we weren't expecting, but was just a courtesy to invite them) and we're expecting about 80 ppl to come. 56 have booked so far, and about 10 - 20 are waiting till the fall to see if they'll be able to make it, or they just want to look for their own deal. I didn't even get 50% of my RSVP's back, most ppl do ignore them. I found out mainly from my TA would had booked, and just from talking to others I know who's still interested in coming. Due to the large size of the wedding, we've decided on doing a private reception with a DJ and dancing. Even with this size we're budgeting $13000, max $15000. This price includes everything! Flight, accomodation, wedding, attire, gifts, photographer, rings, etc. I really don't forsee us spending more than that.
The only thing with having a larger wedding is that I feel more pressure to make sure everything goes well and that everyone has a good time. Ppl are paying a lot of money to come and celebrate with us and I don't want to let them down!
