Most parents, who have a good relationship with their ACs, would've visited their new home long before a year of them moving in. For most families, that's a completely normal expectation, unless you're not on good terms with them ...
They've already decided on a pub meal, so no one is having to do any cooking. And, if the OP had originally expected this, she was wrong to assume so, particularly with renovations going on (if that is the case).
This really isn't a major problem. It's something that can be sorted out quite easily. Even so, I still find it highly strange that a family, who apparently have (had?) a good relationship, find themselves in this situation.
Also, I have to say (because it irritates me immensely), that it never ceases to amaze me how some posters completely get the wrong end of the stick (I assume they don't read the posts properly?), and they end up writing their own narrative, which is completely different to the actual scenario! If you're going to respond to the OPs posts, please read them properly first before commenting, they are not difficult to understand. And before anyone asks why I've not quoted said posts, it's because I've already read the posts, and I don't have time to back through them all to find them again!
CasB, glad you've made the decision to drive yourselves, hope you enjoy seeing the new house!
