Changing holiday dates help

[MakeAWhish]

Hi all. My exH has booked for he and his family and our two children, to go to Portugal next year in July/August. Problem is, I am getting married 4 days into this holiday, he had forgotten, and so now has to change the dates of their holiday so my children can be at my wedding.
Does anyone have a clue at what charges he may incur? I've only just read his message telling me the dates (I am up feeding my 7 week old) and now I am panicking and have no one to talk to about it
If he's going to lose loads of money - I may have to change my wedding instead as so far we've only booked the registry office.

What an absolute numpty! He needs to check the T&Cs of his booking as unfortunately no one here will know without more details.

If he’s booked fully-flex airline tickets and a hotel that can be cancelled until a day or so before travel there shouldn’t be any cost unless it’s more expensive to go on the new dates. If he’s done cheapo flights and prepaid accommodation that don’t permit any changes he’ll lose the lot. The most likely scenario is probably somewhere in between especially if it’s a package; a change fee per person plus any additional cost for the new dates if applicable.

Good luck, I hope you get it sorted!

Thank you @Expressedways
It's an expensive package holiday at a 'luxury' resort, so hopefully as you say, it'll be a charge per person.
Numpty indeed! 😂

I'd say it depends how kind you're feeling!
To be objective, it will be easier to change your wedding date.

How much was the registry cost and would it cause bad feelings on your side if it had to change as I suspect changing dates for a holiday with flights will be quite a lot.

" he had forgotten" how old are dc, could someone fly out with them after the wedding to join rest?

Thanks all for replies. I actually offered to change our wedding date as it would only cost £300 to do so. He didn't want us too - he very reasonably owned up to it being his mistake and told me not to worry about it. I was concerned he'd lose his £1k deposit but he assured me it would cost much less than that. So I hope he's telling me the truth. I'd hate for him to lose that much money when we could change our wedding date, as we've only booked the registry office so far. I would be willing to do that if he stood to lose £1k.

@LIZS they would be 8 and 11 then. He holiday was booked from 27th July-4th August and wedding on 31 July so slap bang in the middle! Wouldn't work to fly them out afterwards as they'd only get 3 days there.
