Holiday - terrible sleeper just in routine HELP

[sososotired]

we are going on a short break next week before I go back to work full time, really excited don't get me wrong but I'm concerned about DS's sleep and routine! We are in a good day time routine and getting better at sleeping at night! I realise it would be disturbed somewhat as we won't be home! I will start letting him nap in his camping cot just that he is used to it when he needs to sleep in it while away!
DS will be 9mo when we go away!
Any advice or experience?

Stick to the routine, take black out blinds and try to time visiting places to nap times. We've been away with DS and always stuck to the routine and he often sleeps better when away, I Think they get more tired out when they're in unfamiliar surroundings!
