Dimensions of Clark Kerr Furniture for Storage & Joining Greek Lif?

About me:
-Placed in Clark Kerr Triple Suite

2 quick questions:

  1. Tried searching room dimensions online and looking at YouTube dorm tour vids, but couldn’t find info I need. Does anyone know the dimensions of furniture in the Clark Kerr triple suites? I want to buy storage but don’t want to buy things too big/small. For example, how tall are the beds so I can know what size under the bed storage I should buy? Or the closets for hanging shoe organizers?
  2. Is joining greek life worth it? Once you get a bid, is housing guaranteed for the next three years if one decides to live in?

Thank you so much guys for your time!
