Rentals of all kinds
At this Hilton Head Island website, they have a list of things you can rent... including baby rentals.
So, on your next vacation, you can borrow someone's child for a week to thoroughly experience the joys of parenting. Screaming kids for hours, McDonald's twice a day...
And there are happy parents willing to pawn their children off on you for a week (so they can vacation in peace and quiet).
*for those not in the know - they don't really rent babies.. it's strollers and such. there was poor phrasing on the site*
