Hi Denise,
Maybe it's a little bit of 'thank you for coming' along with 'we were thinking of things to make your stay more comfortable'.
I went to a wedding in a different state where they gave us a gift bag with chips, chocolates, gum, water bottles, snack stuff that was nice to have and a thank you note. We ate it all.
With destination weddings, I have seen people include items that maybe people will need or maybe don't know they need until they get there, in addition to small gifts.
There is actually a 'sticky' in this sub-forum that includes OOT pictures which could be helpful to decide what you would like the to be.
