Sister brothers wife!

London1984, I don't understand why you wanted to see these people, as you have not made it clear why they were of such interest to you.

If some distant relations turned up at my home unexpectedly I'd hate it unless there was some very good reason for it.

Why now? How important were they that you waited eight years and just happened ? to be in Mallorca ?

I would still leave a message on the phone - or if in the area put a note through the door.
Just say "I know I should have done this sooner but.... "
At least it's touching base with them and you can get ahead of yourself next visit.
Don't just rule contact out. Be apologetic and friendly.
Good luck.

8 years? And no contact at all between you until you just happen to be in the area on holiday? Sorry London1948 but imo you should have contacted them before you pitched up. Missfoodlove is right I reckon.

Imagine the nightmare of trying to live a normal life on Mallorca when every Tom, Dick and Harry, friend of a friend etc wants you to become part of their holiday!

Think you should have contacted them before you went. I hate people turning up.

Yes its been a long time London1948 perhaps you could have let them know you would be in the area first. As Hetty58 said, just leave a friendly message and enjoy the rest of your holiday.

No contact for 8 years, then you turn up in Mallorca and expect an instant response.
You are being unreasonable.

They could be on holiday too! All you can do is try to make contact or leave a friendly note and then get on with enjoying your break.
