I suppose PartyPoker is the only site of the big four that
allows private tables, so since this is just a game between
you and your friends/acquantances, it seems okay to continue
your game there. Just refund everyone the total amount
raked x (multiplier-1)/(number of players) and everything
should balance out.

If there are enough of you to fill a table on a play money
table, that's a better possibility as there is no rake. And
as someone else had already suggested, ultimatebet micro
limits are also rake free but again, you would have to be
able to fill all the seats for otherwise you will often have
an uninvited guest!
