We're planning on getting them:
1 sterotypical gift (flask, money clip, ect) that is mainly for a joke. Also 1 of them is single and likes a good joke, so we're planning on getting him a date barbie.
We're also planning on getting them 4 day ph tickets so they'll enjoy the parks that weekend.
One groomsman is a mac person, so we plan on getting him an apple giftcard
the other likes to drink so we're thinking of getting him a disney gift card so he can drink around the world. (and cash for a taxi so he doesn't drive that day)
We thought we'd tailor it to fit their personalities and likes.
