I agree with Glynis, contact Ros.
Thompson have ruined your wedding night, plus presumably you will lose all the money on your honeymoon suite in the UK.
Re travellingsams advice.
It might be worth seeing if you can get cheap flights at a better time with EasyJet or BA. Could be chepaer than losing your honeymoon suite (and less emotionally upsetting), but I would advise you tell Thomson if you do this as they need to know that you still want the hotel.
Ask Ros' advice as to if she thinks that would be OK because they might have you as a 'no show' if you don't turn up for their flights.
I'm sure every other aspect of your Wedding and honeymoon will be fantastic, try not to let Thomson spoil it for you. Good Luck.
