I went through FSI, Longbeach about 2 years ago. Excellent resource for dealing with the TSA and getting your approval to train (can be a huge pain in the ass if you have never been through the hoops before). Lots of local hotels with shuttles to FSI for around $100-130 a night. My type rating was 10 days long, theres not alot to the citation 500 series.
Hopefully you have a job lined up to pay for this... If it comes down to cost then how much does it cost to replace a citation and 2 pilots who prang at the end of a runway doing v1 cuts? Remember the experienced air north crew a few years back? Not sure how you train for a TR deployment in the real jet either. Its the cost of doing business.
