try starting at day one with the largest family

Answer 6

I got my guess but have a feeling it is wrong what I did was lay out the nights the families stayed.
J- 1-10 2-11 3-12 4-13 5-14
C- 1-5 2-6 3-7 4-8 5-9 6-10 7-11 8-12 9-13 10-14
E- 1-8 2-9 3-10 4-11 5-12 6-13 7-14
L- 1-6 2-7 3-8 4-9 5-10 6-11 7-12 8-13 9-14
B- 1-8 2-9 3-10 4-11 5-12 6-13 7-14
Then crossed out the days that the families could have possibly started staying so all on day 1 was crossed off until none had days in common
