I think a little something is a nice gesture to say thank you. I plan on doing tumblers (From the dollar store) and adding waterproof labels to personalize them. I'm handing these out at the airport and people can stuff them in their carry on. I may put a few things in them but I haven't fully decided yet. The OOT bags quickly adds up and I also have close to 50 guest attending. The maracas are a great idea, I even heard of some people using them for getting the groom and bride to kiss.
