On our trip we did 7 days at Disney and hopped over to Universal for 2 days. At the time our daughter was 10, and she worked hard and managed to earn herself some money by doing chores, helping the grandparents etc.. and with what she earned plus some extra we and others gave her, she took about $120 U.S. with her. She managed to get herself 3 different Disney shirts, some Universal souvenirs, an autograph book plus a few other bits and pieces and she had about $25 left over at the end. I asked her the other day if she felt she had enough money and she said she had no regrets.
