There are two ways to disconnect, and a couple different ways to reconnect
as well.  C-a d will disconnect the screen session, but leave you logged in;
C-a C-d is a "power detach" which also terminates the calling shell.  This
is what I do just before going home.  

Then on the other end, I do 

ssh colohost -t "screen -D -R"

Which says, shell over to the colo host, and make sure the screen session is
actually detached if it isn't already, then reattach it here and give it to
me."  Now, if you run more than one session, this can get fun... OTOH, you
can name them and attach by name if you wish.  I'll leave that as an
exercise.  But C-a C-d and screen -D -R is what I use.  YMMV, IANAL, EIEIO.
