Am late to this post. What's new?
I always cooked before a holiday when mine were small and froze the meals. For 10 years we went to a family owned house in Scotland, my ex never came, it was always me and the kids, sometimes friends plus kids came too. If they came they brought meals too.
That way almost no cooking. I wouldn't have had room for TMX in car even if had one then.
Shepherds pie, fish pie, bolognaise, stew, pizza, chicken in BBQ sauce, hotpot.
I only had to cook rice, or pasta, or it was an all in one meal.
It was cheaper too as food didn't come out of my holiday budget.
Hope you had a good time.
Even with TMX I'd still do same given time over again.
