Examples of sites using WP Travel Engine?

Hello,
I am still thinking about using the all access package for my sites, but i would like to see sites using WP Travel Engine most complete package, to see if it suits my needs.

I manage a quite large tour operator with more than 40 destinations / 300 different tours, most of them with different set dates for groups, so I can’t afford a fail.

Is it possible to include different payments, such as wire transfer / checks / our bank’s online payment solution?

Thank you for your help!
