We have a big trip planned for Christmas this year. A brief rundown. Myself, DH, DS 5, DD 7, My father and his wife, My DH's mother, sister and niece DD 7. My brother, his wife, their 3 kids DS 9, DS 7, DS 2. Boy when I line it all out I get scared! 
Anyway what I booked were 2-2 bedrooms. I requested each of them to be lock offs. So this is my plan for sleeping arrangements.
Room 1
Me, DH in Master (of 1 bedroom lockoff)
Father, MIL (in studio part of lockoff)
My kids DS 5, DD7 (in LR of 1 bedroom lockoff)
Room 2
MIL, and SIL, Niece (studio part of lockoff)
Brother, SIL (Master of 1 BR lockoff)
Nephews (3 of them) (in LR of 1 BR)
Is this going to be too much? I was going to try for a GV plus a studio but no such luck.
Second Question: If we don't get the lockoffs how is that going to work with the bed situation, better or worse? I guess I am confused as to what type of beds will be in each room depending on if we get the lockoff or not.
Please help!
Thanks
