I go to t3, not crew but varying times of day. Yes it can be scary but the old adage of assuming everyone is trying to kill you helps keep you on your toes. T5 has a similar bike Park area,near the bus station area I think? Itll save you a lot of time at rush hour,just depends how much luggage you have and how easily you can store your riding gear. On the whole I'm glad I do it, i reckon my total time saved on my commute over the last year must be about 30 hours,no exaggeration!
