You will not need to worry about paying for food (meals may be expensed and you get per diem). Usually one rental car given for every 2 new hires. Hotels during training will normally be a suite-type with kitchen.

After DFW Company Indoc & Part 135 you will be sent for aircraft specific type rating. The preferred training locales are MCO and DFW but its all based on course availability. STL is possibility for Praetor also. Flexjet is in the process of building a training center in partnership with SimCom in MCO but not operational yet.

Plan on at least 3-4 weeks straight but it could be broken up. Recent new hire friend had 5-7 days off at home after each phase. YMMV!
