During this week I would normally be faced with amazing fish and chips, crab burgers, muscles and frites or fresh bread, wood fired roast beef and potatoes, chips in duck fat with crab sandwiches. And that's before we consider holiday cottage family packs of crisps and tubes of Pringles. Oh, wine, gin and repeat. I'd expect to see half a stone on in a week and 2 Months off! Especially when you consider the proximity to Xmas
While undoubtedly holidays aren't (generally!) a time to deprive yourself, you also need to consider the impact not only on your weight but also your mental health if you are to indulge yourself so fully for just a week.
Just remember all the posts you've made bemoaning the fact that you can't lose the last 4lbs, or that your weight has gone up because you fell into the biscuits after the wine.
And, as you rightly point out, why would you do this to yourself just before Christmas, when you're implicitly (explicitly?) acknowledging that all bets will be off when it comes to low carbing?
Surely there's a middle ground here? Does it have to be high carb every day? Can you not have, for example, crab burgers without the bread, moules and frites without the frites, roast beef with vegetables and not the potatoes? Don't buy the crisps and Pringles - if they're not there then you won't eat them. Don't plan to cheat, in other words!
If you want evening snacks, then why not a good cheeseboard? You could have roasted/salted nuts - still carby, but much less so than crisps, and with a bit more nutrition.
In other words - you need to plan your week so that you minimise the damage. Don't fall into the sort of acceptance that you have to eat these things. And try and change your mindset about what being on holiday means.
It won't be much of a holiday for you when you get back to find that you've gained half a stone, with Christmas also looming on the horizon!
Sorry if this sounds harsh - I realise that the Big Stick should be in the cupboard right now! - but your post just reads that you're going to do all these things, and then complain about weight gain when you get back. And I know how hard you've worked to get where you are right now.
Why would you throw all that hard work away?
