Im a student, therefore im poor.

now the issue i have is that on friday (when Warmachine is on) i shall have enough money to pay for that session, but not for the LOTR tourney on saturday (which ill have the money for on the saturday) this is due to my works stupid ways of paying me.

so my question is, is it possible for me to pay for the sessions im attending on the day? or just pay half of the get wrecked fee over 2 days?

No idea, one for the Conquest guys on the day.
Pretty sure its pay per session now though with no rego fee.

Shouldn't be a problem.

At the end of the convention, the people on the rego desk (probably Emily) will generate a report from AON, showing who still owes money for any of their sessions. As long as you pay for the LotR tournament by the time you leave on Saturday, you'll be fine.
