If you give people glasses instead of solo cups, I find that partygoers will tend to treat your house with a lot more care and respect. We have a set of glasses that have little black stickers on them that are a material that works well with chalk, so people can label them.

Yes, there's a risk of breakage & having to clean up, but overall I think it sets a better tone.

Dixie cup / glassware divide will tell you a lot about the type of party, but not always along the lines you might think.
