For the climate, it depends how warm you like it - all of our departures for 2015 are during "summer" months - for a rough idea of the highs and lows I'd recommend that you visit this website which gives you the averages for Tennessee for the year.

In terms of flights - our team are in the process of getting these in place (a problem with airline schedules coming out after brochures have been printed) but I've given approximate details below.... All flight details would be confirmed in your final information.

If you fly via Chicago you'd be looking at about 11hrs in the air + connection time

If you fly via Dallas you'd be looking at about 12hrs in the air + connection time.

Inbound
