Various dates. Check out USAirways site to see cheapest dates and then enter them into opodo. Total package is less than flight only on USAirways. Extending the stay 3->5->10 days seems to make little difference to he price.
My previous thread for 3 nights went quite hot for a similar price. Hope someone finds this useful
