I have all my little envelopes from the
Disney Store filled with Disney Dollars with up to 20% tip for each meal. I did like several other posters and figured the tip amount. I got the bills in denominations that would allow me to tip 15%, 18% or 20% and not worry about breaking a bill.
I start about 6 months in advance picking up a few Disney Dollars at a time. I don't just set aside regular cash because I know me, I would slip money here and there as needed. But you know what, the pizza delivery man won't take a Stitch $5 for that pizza delivery. I do this for more than tips. I have a list of things I know I need money for and I just pick that up here and there as the monthly budget allows. I probably have $600 sitting in my jewelry box ready to go in March.
