A lot of dislikes/Vegan/Coeliac/Low carb/whatever, and you were invited to stay at your other half's family's home for a couple of days.
A)Expect them to cater for you but help out?
B)Try to engineer mostly/always eating out whilst there?
C)Take your own foodstuffs and offer to help cook or make your own meals whilst there?
I think A) is a bit too presumptuous and I would worry it would stress them out and be rude, B) might not always be practical and depending on the dietary requirement, may still mean you couldn't eat suitably, and C) might seem rude, too..
I know it depends on the condition and also on the knowledge, accommodating of the person you're staying with-but in this case they get on very well but have never been in this situation so It's difficult!
