If you have that much experience, the CTP is a bit of a joke. It's designed primarily for 1500 hour SEP CFIs who are moving to their first jet and first airline. Assuming you've already flown a jet airline, it's going to be an expensive week with not a whole lot learnt (maybe some useful networking). So I'd recommend finding somewhere cheap since nobody is going to ask where you did your CTP. I hear Aerostar in Florida fits that bill. That way, you also have the option to get a Type Rating on your licence.
