I've found some really useful information searching the forums, but am still looking for more info relating to my teen daughters trip in April 2011 (four full days and travelling both ways overnight)
It will be here first trip without me to budget for her!
The difference with teens compared to adult travellers is that they cannot buy travellers cheques, or a prepaid card (at 14 years anyway) , and I don't want to send her with a large amount of dollars - her visits to museums etc and breakfast and most evening meals are included - her spending money is more for bottled water (or other drinks such as fruit smoothies etc) and lunch time and snacks (like me she is a chocoholic!!). Then theres the shopping ....
How much is bottled water, roughly how much are snacks? Has anyone recently used ATM's in New York to convert pounds to dollars (we know there is a minimum charge of £1.20 per transaction plus possible local charges but perhaps the dollar rate is better than the £1 = $1.52 that we can get on cash in England?)
My plan so far is $50 in cash (for 4 full days) and to take her bank card as a back up - I know that what to allow for her to spend on clothes is a personal choice - she is hoping to get some cheap bargain clothing if the teachers allow time to shop and a few souvenirs - postcards and that.
