Flight cost vary according to time of the year I recently flew with Virgin (Virgin sale) for a two week trip £235-00 always if you can avoid school holidays. Flights from Manchester nearer to home American Airlines or US Air can be similar.
Flights from Miami to Freeport Grand Bahama if booked in UK £180-00 TO £210 but if booked in USA same but in dollars. If you know anyone out there get them to book it for you.
Food prices in Bahamas more or less same as USA. Eating out three course evening meal bank on $15 to $20 for something half decent.
To reduce cost try eating at the native fish bars, the food can be stunning. Local beer Kalik very good at $3 per bottle.
Car Hire $30 per day.
Petrol just gone up from $4 to $4-50 per GALLON!!! Tragic
Drive around all day its almost free.


Hope this helps.
