주말 잘 보내세요 or 좋은 주말 보내세요. Which way sounds more normal (using informal polite)
Does it matter? I see both when I google, but I am not sure what is more common when expressing it to friends and colleagues. Should I use the 에 particle for 주말?

감사합니다.

Answer

Both are fine to use. But I use "주말 잘 보내세요" more often when I talk to friends and colleagues and "좋은 주말 보내세요" when I send a message or an email.

No need to use "-에" for 주말.

Answer

Both are good, but I am personally more comfortable with the first one.  좋은 주말 sounds slightly more formal to me.

In both, 주말에 is almost ungrammatical, because 보내다 (pass the time = to live / get by) is a transitive verb working on the object 주말.  주말을 is grammatically okay, but adding 을 makes them sound worse.
