In secaucus quite regularly and the hotels are likely to be able to shuttle you too / from KTEB
Also you can ask your FSI associate for special rates, they always can provide them in hotels around the training center.
I wouldn't recommend Manhattan also, but a bus ride will get you there in 20-30 mins, cabs are more expensive but flexible.
Tip: set a rewards account with whatever hotel chain you end up using, 25-30 days might get you a few perks in the future.
