Activity for Kaitlynn

Okay, I need etiquette advice on inviting an old teacher/family friend to my wedding. I definitely want to invite her, but I never even met her husband. Is it bad etiquette to only put her name on the invite?

So, my FH and I are realllllyy wanting to go on an Alaskan Cruise in early May of 2019 as our honeymoon, but everything I've looked at so far seems crazy expensive. Has anyone done an AK cruise? What cruise line did you use, and did anyone find good...
