This had me lol'ing as my mom holds the money for my parents trips but I know my dad has a secret stash!
For us we aren't deciplined, if we're having fun, we'll get more money out since we don't bring a lot and the atm limits are what caps our bankroll.
For a local visit, 2-300 max (sometimes we lose $50 and stop because it's not fun so we'll go to dinner or something) no atm visits there, but trips, we just want to have fun! We also cap limits based on prior trips, so one weekend it may be $400 bankroll, another weekend $900, it really depends!
