Meeting in London I’m afraid.
With respect to the money situation there are a number of websites that you can visit in order for you to find the cheapest way of getting your travel money (from money exchange to using your cards abroad).
A card is offered by the agent that I booked my trip through which can be charged up with your spendo, but again there are charges for accessing your own money, which I disagree with. Tips would be if you are going to take money out at the cash point more and less frequent would be cheaper than little and often.
Also retailers abroad will offer you the option of paying in the local currency or your home currency depending on the card that you are using. This is known as dynamic currency conversion, which can be expensive if you choose to pay in your home currency as the exchange rates that they apply can be less favourable.
To help you with how much to take. Top deck have provided you with details on:
This will help you to plan how much you are going to need, not including spendo for various bits on the way. I think it would be sensible to budget how much you are willing/able to spend per day, and if you are considering going to bars and clubs along the way this can expensive so build this into your budget.
I think Euros is the currency that we will be using for most of the trip and i know that Switzerland has not converted to the Euro as yet. It may be worth investigating what currencies are going to be needed and where.
Hopefully that’s enough to help you all with your planning.
