@JucoDad In college, my husband and his roommate (Kenny was the shorty at 6'5"...Springer was 6'8"... they had a footer on the team as well) had the long beds and they still weren't long enough. So they bunked them and got two extra mattresses from the school for makeshift king beds. LOL
From what we know (see point 6. of my summary above) they will not be with host families but will stay in the apartments. It will make a huge difference not just in costs but in terms of flexibility if they get moved around from one team to another...
