How the world has changed from 20 years ago when we used to put a couple of grand on pre paid FX debit cards and take quite a bit of cash for our family holidays
That's how I used to do it.
A Legacy Santander zero is a fee free grandfathered credit card that gives the same FX free conversion as the Halifax Clarity and is no longer available as a new card.
I had something similar, but when the card was updated, I lost the free FX conversion, and there was no record of it on their system, and I couldn't find the letter that confirmed it. Years letter, when shredding lots of bank statements, I found it - but the world had moved on
FX does incur daily interest from time of ATM withdrawal so either pre load (or pay off at once via the app)
I remember someone saying they did this, and had to repay straight away, by the evening you had accrued a few pence interest ! There was a debate for a long time about whether withdrawing on a credit card tanked your credit rating.
I never thought there would be more than 110 replies to my question
I am just off to collect £100 worth of pre ordered euros as better be safe than sorry

With regard to Germany, and as a seasoned, regular traveller to there, I think that's very sensible. If you pull money out of an ATM (hopefully fee free) whilst you're there to replace it, then you won't need to order money for the next visit - as I said above, the exchange rates at supermarkets and the Post Office are shockingly bad - often 4-5 cents per pound adrift of the actual exchange rate. One of the things you will occasionally encounter there is an establishment that plasters its windows with Visa/MC stickers, but then moans about you paying with a card. There was a statistic oft quoted on travel blogs that the average German carries something of the order of €110 cash on them - I think the UK equivalent was something like £20. It's definitely something cultural.
