Hi to all who have posted messages - I'm Sue Davies, tour manager on this tour. I've done this Rockies tour a number of times and it is fantastic - lots to see and do and the most spectacular scenery. As far as the optional excursions go, just to clarify, payment should be in cash - you can withdraw Canadian dollars from ATMs using your debit card (remember to tell your bank you will be using the card) so this is a secure way to do so. The helicopter ride can be paid by credit card direct to the flight operator on the day. I'll give more details of all the activities at the start of the tour to help you decide what you'd like to do to make the most of your time. I'm sure we will all have a great time! Look forward to meeting you soon, Sue
