Most have nice pools
treat yourself to a pass for Disney
Six weeks in the USA to do a PPL and I think it's unlikely that "cityjet" will have time to laze by the pool and go off cuddling Mickey.
My view on this echoes tangovictor's. If your weighing up the differences between the the US and the UK I do believe the benefit of cost has gradually eroded away over time in the US. The UK's clubs are offering some great deals in certain places and you will be doing it at the time of year with the most daylight hours and the likeliest chance of some good weather.
Does it HAVE to be done in six weeks. If it crept into seven or eight would that be a disaster?
