Hoping to get some suggestions for traveling & meal money for my 17 y/o and 15 y/o traveling to WDW in March with their band. They will be on a 24 hour bus trip to & from Disney, then 4 days at the parks. They will have to pay for all their meals, so there will be a lot of money involved. This will be their 1st trip of this magnitude alone. We've always toured the parks together and I have always carried a mixture of cash, traveler's checks & plastic. I am concerned that if I give them cash, it will end up lost or their wallets forgotten. Traveler's checks require and ID to cash them and my older son does not have a license yet. Has any fellow DISer's sent their kids with the traveler's ATM cards? Prepaid debit cards? As a side note, I will be flying there to watch their band performance, but will be staying at a different resort and allowing them to do their own thing. Any ideas?
