Background is.
We live near my family, they pop in all the time, we spend far more time with them than my DH family although we do see them regularly and there is no tension - everyone in very nice.
Each year we go on 2 hols, 1st our 2 week family holiday, 2nd a weeks staycation with DH family. Its a great opportunity for cousins to get together and play and wonderful memories for children etc.
I usually like to do our family holiday 'just us' but my DB is keen to share a week of our holiday.
We did it this year, no issues but I really do like that 2 weeks for us as a family and hate considering others when booking a venue etc
How do I get out of it next year without causing offense. We see my DB and his kids at least once a week - lots of dinners, days out etc whereas DH family is concentrated in that one week,
