Hi Trish
We will send you a full list of excursions about three months before you travel but the short answer is yes, you can pre-book some of them. The Palm Springs Tour and the Rat Pack show can both be paid for in advance, and if you book them both together you can save 5%.
I haven't used a money card but most travellers seem to be quite happy with them. I find travellers' cheques quite inconvenient when I am travelling. Personally I would take cash and cards, withdrawing money from ATMs as and when I need it. Let your bank know if you are thinking of doing this.
Kind regards,
Olly, your editor
