we're doing one welcome bag per family/couple/single for a total of 24. we bought the personalized bags from southhorizon.com on sale for $2/each. we're including a mickey mouse plush, wedding candle bought in bulk, palm tree journal, sunscreen from the dollarstore, ghiradelli chocolate bars, personalized water bottles, oranges, a initiary of our events & wedding day schedule along with some misc. snacks like pretzels & muffins. we also want to include some disney dollars. there are also 9 kids gift bags we made from bags from cheaptotes for 99cents & then personalized with each kids name with supplies from micheals craft store for 9. we are including disney books on clearance from barnes&noble, glow in the dark swords & crowns from the dollarstore, animal puzzles, mickey mouse playing cards from walgreens for $1, disney fruit snacks and then baby items for 3 with gerber baby food, bear in the big blue house bibs, bottles & pacifiers from the dollarstore and wetwipes. we have bought everything but the food items & in the end it will be about $600 for all the bags. our em said the resort will hand them out at check in that we just have to get them there & have them approriatly labeled with reservation #, guest name & check in date, which will be easy as we're taking care of all our guests rooms/reservations.
not sure if you want to do all that but even a simple bag with an itiniary, some wdw park maps & bottled water is great for your guests. i responded to your other thread about newsletters too icgymnast if you want to pm me i'll send a copy of ours, you might also look into posting your wedding info & events on your disneywedding webpage or creating your own with theknot.com its been a great relief for us & helpful to our guests.
best of luck!
