Thanks Chimilady
I budget that amount for souvenirs because I figured the average t-shirt is $30 and if we wanted sweatshirts they might be as much as $50 - so that was enough for one tshirt/sweatshirt for each of us....
Restaurant tips - I took all our restaurants and chose the highest priced meals at each of them and added a 20% tip -
for OOP I took the four top choices of restaurants, figured the highest priced meal at each added in a 20% tip and then took an average of those four prices and mulitplied it by 3 because we may have three out of pocket meals...
for unexpected things - I was considering something going wrong with the rental car, someone getting sick, a problem with our flights, etc. - I figured $500 would be enough to cover any unexpected emergency that might arise
I thought I had done very good research and my final act of research was putting it out here for the expertsbecause I am a newbie but I like to be prepared for any situation...
It sounds like you did a ton of research and really have a plan that makes sense for your family. Looks great to me!
ETA: No need for cash. Except for mousekeeping, I literally can not think of one time when you would need cash. I had $20 in my wallet when I left home, and the same $20 in my wallet when we got back.
