Bridal Party Gifts...here's what we're thinking.

So I am obsessed with YETI tumblers etc to keep my drinks hot/cold and our friends love them also. I found these flask tops for the tumblers that hold 5oz of alcohol so you can take it with you and make drinks on the go for tailgating, beach day, etc (I use mine all the time and it's awesome). We were thinking of getting the tumblers personalized with their names, a bottle of their favorite alcohol and the flask tops. We are also giving them a hangover kit and some other swag in the package and we figured we would hand them out after the rehearsal. I know they would all use them. We're all in our 40's and this is definitely something I would give any of them for a birthday or Christmas. Thoughts?
