[Closed] Travel money - best options?

Hi all,

Going on holiday on Friday, and only just started to think about money...

After a couple days in Germany, we (gf and I) head to Malaysia for 7 days, and then to Thailand for 12 days.

I've done a bit of reading on MSE, some good advice, but still not too sure about where/when to convert money.

Initial idea was to just take out £200 worth of Malaysia Ringgit, and £300 worth of Thai Baht (we're doing the whole holiday on a budget, we're staying with relatives first couple nights in Malaysia, and we've booked accommodation for most of the other nights in MY).

However, not too sure if I want to be carrying all that cash through Malaysia before we even get to Thailand.

I have Natwest debit and credit cards, from what I can work out to withdraw abroad with the debit card it's 2.75% plus 2% up to a maximum of £5, so would make sense to take out larger amounts of money in one go.
So maybe just take out £50 worth of Thai Baht, and take out more once we get into the country?

So also, any recommendations for where to exchange currency over here (if I go for £200ish Ringgit and £50 Baht), considering I need it by Friday? MSE suggests this is the cheapest, anyone used them?

Credit card wise, transactions just have a 2.75% fee, so would make sense for hostels etc. However, I'm always a little cautious about using cards in general abroad- or is that just me being silly?

Ta, Duane.
