LOL ... that's too funny. Well since you know Ariana Grande you are already a cool Dad!

Just come up with a t-shirt they will want to wear and want to keep after the trip. It will be a keepsake and a reminder of good times. Make one extra for your daughter and put it away for her. Give it to her in her Christmas stocking 20 years from now.

I still have a t-shirt my parents gave me that's 50 years old. It has a picture of our cottage in Muskoka and my dad's old Gravette on it.
