Agreed with the above. My 25 hours will work out about £110 an hour once I add in flights and accomodation etc. I could do this cheaper in the UK as a have a share in an aircraft that is £70 an hour.
I do however only have 1 week off work and need to get these hours in a short space of time. I wouldnt like to gamble on being able to do this in the UK during the winter. If you have plenty of time though it might be the way to go.
Good luck whatever you choose.
