my husband and i are going to london in October. Tube questions:
1. does a credit card cap your daily amount like the oyster card?
2. can a credit card be used for 2 people (tickets) at once or do you need 2 different credit cards?
3. i take it you tap in and then tap out, same as oyster?
so essentially my question is what do you do for 2 people? i know if you have oyster cards each person needs one. thank you-annfloam
