i'am still thinking about going to this con, does this mean if i don't register untill friday i can't come?

I think you still can go if you dont plan to get a room on the hotel.

as It stated attending-only is still open.

Witch means you need to pay your entrance fee at the hotel butt need to get yourself a sleeping spot in other location ( like at a friend or your home or another hotel )

We will close the online regsitration today, yes.

You can still come to hotel and buy a convention ticket there on location but we will not be able to give you a room (as we are simply sold out) so you will need another place to stay for the nights.
