I went to book tickets for the following three people. Ronald Collis age 69, Maria Collis age 42, and Pamela Collis, age 13. The trip was arriving in Rome November 6 staying 3 nights then arriving in Venice, staying in Venice 2 days then leaving for Florence staying 2 nights, leaving for Rome. The cost that showed up was $93 for Pamela and $124 each for myself and Maria Collis. However, site would not let me check out. Can you help me with this and tell me how can I pay for the tickets.
