Adult Co-ed Slumber Party Ideas

I have 10 close male and female adult human friends traveling to my house next month for 3-4 nights of concerts and local activities.

Looking for ideas on how to stock my house, thoughtful things to have on-hand, tips and/or tricks for making everyone feel welcome.

If you had 10 guests coming, how would you prepare? I have sleeping arrangements sorted but may need to grab extra linens.

Note: These are not couples. They are my good friends who travel for concerts. Everyone is 30+
