Hey so my sister and me have 5 kids between us. We’ve both been before with our parents but not together. I’ve got a 9dd 11dd (starting secondary in September) and 12ds. She’s got 15dd and 17ds. When they go they do activities but we don’t usually. She’ll bring her hubby but I’m divorced so there’ll be 8 of us.
We have booked 2 lodges for the 8 of us and our 2 parents between Christmas and new year (27th to 30th). My sis has been at Christmas before but this is cheaper for us with only 1 income. So I finally come to my question, sorry for the length, do you have any tips for a big age difference and height difference 
. And what activities would you recommend for them all to do together? Thanks for your help xx
