There has been a lot of talk on earlier threads about how Ari Ben manage to charge such low rates. I just checked and the search function is up and running again so I suggest you have a read of previous threads. In summary though it is all about 2 guys flying together and if you are JAA then you will only get to log half the hours. Also the aircraft are flown 24/7 with preference during the day to flight training so expect to be shooting around Florida during the wee small hours.
Think you will find that the effective hourly rate is probably on a par with others that you will find but you will have the flexibility of being able to build your hours during daylight and take in some of the sights.
