vpn

I just started using VPNBOOK, which is a (very efficent) free VPN solution.

I have a question:

VPNBOOK user and pass used to connect to their vpn network are publicily available on their homepage; everybody uses them to connect to the vpn.

Can a user intercept my wifi traffic and:

Understand that my connections are directed to VPNBOOK servers.
If point 1 is successful, then they could use VPNBOOK public user and pass to decrypt my traffic?

I hope I am missing something, otherwise it would be a very big weakness and I would revert to a paid service (with a private account)
