I think that’s fair. It can also be very difficult to say to a family member, ‘Look, we find staying at your house stressful/difficult because of X’, when the family member in question clearly has no idea, because that’s their ‘normal’
Especially if the person who really struggles is the married-in partner/spouse, as is often the case, because they didn’t grow up in the house/with those norms.
My foreign SIL couldn’t get over how rude she thought our PILs were being when she and BIL came on visits to DH’s parents (MIL in particular well-meaning but unimaginative and tactless, and incapable of seeing someone else’s needs don’t always coincide with her ideas of hospitality).
I posted jokily about this on here before (thread about weird things your ILs do?), but PILs’ only loo/bathroom is downstairs, just inside the front door, across from the living room door, and has a frosted glass door sited so that anyone sitting on the loo or drying themselves after a shower is in full view of the living room, hallway, anyone coming to the front door, only lightly masked by the frosted glass. I mean, you can see who it is very obviously, because the bathroom is tiny, so the glass door is only a couple of feet from the loo.
As I said on the other thread, one SIL arrived once at the front door and complimented the new hairstyle of the other SIL who was on the loo.
DH grew up with that, but other people (including our son) tie themselves into knots trying to avoid using the loo when there!
