Ok, so my fiance's air force friends have invited us to both the prewedding celebration and to the destination wedding. We have to try and figure out what to do about a gift. They got us for our bridal shower a very nice gift and we are extremely close, so we were wondering how the gift giving in this case works. With it being a destination wedding and the added cost of flight (big) and hotel, etc...what are the gift expectations...and are we expected to bring one to the prewedding celebration as well?
