We've done it many times. We're just north of Boston and most times send a box UPS ground about 4 days before we plan to arrive. I'd say we use a box about 24" x 10" x 18" "ish".....let's just say it's big enough to send down 12 waters, 2 boxes of pop tarts, chips, crackers, granola bars & lots of other breakfast foods/snacks and a few toiletries. We always end up with more food than we can eat. My husband seems to remember it costing us about $30. The only difference now is that some of the resorts that have convention centers attached to them charge a delivery fee for these boxes, so I guess you have to take that into consideration along with the shipping rates to see how worth it it really is. We believe it is worth it because it saves us a fortune in breakfast and snack expenses even with the shipping charge. The only time we haven't done it is when we have already planned to have a rental car...in that case we just run to a nearby store.
