I considered handing the bags out prior to our departure, but decided against it. I wanted the guests to actually take the items with them, I was worried that it I game them before they wouldn't take the items.
I am also having my parents and my brother take the items with them, they will be in Aruba a week before me so they are actually going to put the bags together prior to our arrival and deliver them to the hotel. (They don't know all this yet)
