I am making one per couple and I think they will end up being about $25-$30 each. Maybe a bit more, but we are only making 7 or 8 of them since we are inviting immediate family only. A lot of the thing I am putting in them are small so I think I will buy a space saver bag to bunch up most of the clothes and hopefully that will leave enough room in our check back for the other wedding stuff we are bringing. We also plan to buy stuff to put in them when we get to Hawaii (like soda, beer, chips, water, and cookies). I have a line on the RSPV for people to let us know what day and time they are arriving so we hope to meet up with everyone upon their arrival to give them away, We will not be doing favors. I bought by bags off Vistaprint with a Groupon and in addition to the stuff everyone does (like Tylenol, Advil, Pepto, Band-Aids), I am also including a pineapple shaped bottle opener, coozies that look like Hawaiian t-shirts, and beach mats. Good luck!
