Our friends and I will be on the Ruby starting June 19th.  I'm so used to early/late dining as they coordinate with the show times, and I prefer eating later so that I can go to the gym and wash up right before dinner (like after a port).  In this case, I've booked all of us in the MDR for dinner at 7:00 for all 10 nights.  Will we have enough time to eat and walk over to watch the show?  I just feel like I lack info.  Thanks!
