I went on this tour a few years ago, unfortunately you need to take a vast amount of money, as you will be buying lots of lunches and dinners and also coffee and cake stops etc...so that needs taking into account. Also many of the optional extra were paid in cash, so I took to cover that, although I only managed the helicopter to Franz Joseph as the others didn’t happen due to weather conditions. Also when I went the excellent tour manager added in 4-5? Extra trips these all mounted up so do allow for extra excursions you don’t want to miss out on anything as it’s a long way to go back..
I know you have travelled before so I am sure you can work out a daily food allowance and then x it by the amount of days, plus optional trips, souvenirs etc it all mounts up. I did come home with money but only because the other flights didn’t happen.
Take as much as you can, plus credit cards, etc... it’s a great tour, there are some long drives so catnap when and where you can.
