Two rodlin in an establishment as shabby as the Platinum Goblet is indeed quite a lot, particularly if all one got was a spot on the floor, and a minor businessman such as the proprietor of a small tavern is indeed unlikely to accept Melenian currency, which would be the copper coins you speak of. In Rodoria rodlin is the only kind of coin, and they are quite valuable.
(EDIT: It also occurs to me to mention that even if the tavern keeper did accept Melenian coppers, two such coins would be nearly worthless. He'd be more likely to receive a scoff and be shown the door than to get a spot behind the stairs for that kind of money.)

And yeah, I have to agree with Shien that I'd prefer if you left the actions of the NPCs (which I said earlier that I would be controlling directly) to me... it would also mean that you actually had something to [I]do[/I], rather than just write one post like this and then wait for other characters to catch up on the point in time Kaedan is occupying.
EDIT 2: That is, the NPCs in the tavern; you don't have to change anything from before then.
