Ok, so... I may have gone a little overboard...
Each bag will be getting:
Personalized beach bag
Welcome letter (with wedding day itinerary on the opposite side)
Wedding week survival kit which includes:
a deck of cards, hand sanitizer, mini lint roller, chapstick (SPF 15), aloe vera gel, 2 bottles of conditioner, q-tips, bobby pins, hair ties, med-lyte, pepto bismol, tylenol, match sticks, gum, dramamine, photosharing info card, roll of tums, sqwincher, shout wipe, and vitamin c.
waterproof keycard holder with insert (and spanish phrases) and lanyard
2 personalized koozies
2 stainless steel mugs with thank you tags and sharpies (so they can write whatever they want on it while they are there)
cigars for the guys
and pashminas for the girls
There will also be a handmade ornament with a map of the DR on one side and our wedding logo on the other... haven't decided whether this will be in the bag or on their plate at dinner as the favor.
