that will depend on where you are and how you have travelled but either way just book a flight, boat, car or whatever back home again with whoever goes that way.
where are you and where is home ? does it involve an air ticket and if so is it for fixed dates to return, if so you would have to buy another ticket, give us a clue.
I was on holiday in Majorca a few years ago. One holidaymaker was crying and swearing at the rep, saying she wanted to go home immediately. We later found out the reason why. There was no HP sauce at breakfast time. Solution, the rep went to the shop and bought a bottle. I am not saying that this posters problem is trivial, but think about it, you're on holiday enjoy yourself and sort out the problem when you come home.
Why didnt the holiday maker bring a bottle of HP sauce with her ? was she a bit "dolly dimple" ?I have never before heard of someone's holiday being ruined over something as trivual as that !
