Hello! I'll be visiting Old Trafford for the first time and had some questions about tickets. I am already an official member, so I believe I've completed the first step in purchasing tickets! Questions below:

I will be in Manchester on 12/31. I realize this will be an extremely popular match, and the site shows that tickets have already sold out.

• I see that Hospitality tickets are still available. Are those worth it? What is the best package (Europa Suite, Museum, etc)?

• On the ticketing site, what does "Date and KO TBC" mean? Are the dates and kickoff times not confirmed yet? When do they get confirmed? Picture of what I'm referring to - http://imgur.com/a/jnRKW.

• Are tickets safe to purchase on Stubhub? I'm coming from the US, and have often bought tickets for sporting events on Stubhub. Is it equally reliable in the UK?

• Despite the site saying tickets are sold out, do additional tickets ever become available? I realize this is a popular day to go, so not betting on this happening, but still curious.

This is my first visit to Old Trafford, so I don't mind paying for hospitality tickets despite how expensive they are. Thank you in advance for your help! Please let me know if there are any other factors I should be considering.
