337 Boot Camp?

[Jhogan0101]

Hey all, hoping to purchase a 337 in the next couple of weeks.
I can train at my local FBO but it may take a long time.
They are booked out about 5 weeks and then it is sporadic after that.
I was thinking it may just be better to just take off a few days from work and just get the endorsements/rating that way.
Anyone have any suggestions?
I live near Philadelphia.
