Dog not settling on holiday

[illmonkey]

This is louis 3rd holiday this year, he is only 1, previously he would find his spot and be ok, this time he is just walking around crying and starring at the walls like there is something there. He does this at home, but usually it's a phone reflecting onto a wall or something.

Any ideas how to calm the poor bugger down? We're worried he won't settle for sleep tonight.

He's got his bed and a blanket, but he's not intrested, even to come up on the sofa (not that he is allows in this rental cottage!)

He did last night, by 10:30, he was nodding off (on the sofa).

Today we done 8+ miles, he was crying for 5 minutes before falling asleep infront of the fire. Will go to the local vet tomorrow for some backup spray.
