We will still be able to go on holiday.
Yes, but it won't be as easy.
Result: Bad
You will probably need to get a VISA (increased paperwork/costs), and there will be additional checks when you're at passport control (i.e. longer queues at airports).
So yes, you will still be able to go on holiday, but it will not be easier or cheaper.
And with the decreased value of the pound, it's likely to be much more expensive to go on holiday to the EU.
If you disagree, or would like to add more details, please let me know.
You can suggest a reason for leaving the EU, or look at the other reasons.
