Any ideas on spending money needed for a 17 year old girl who is going on a 5 day trip to New York next month (with school)? Trips included in cost of holiday but she’ll need money for food, subway and spending. I’ve worked out what she needs for food and transport but no idea what she’ll need for spending. Is £50 a day enough or does she need more? Has anyone else has a child go on a school trip to New York? Never been myself!
