Me and Hubby are in the extremely early stages of planning a vow renewal for our 7 year anniversary. It'll be in Vegas so a destination wedding I guess. Because we know that this would be a bit tough for some people we are planning on paying for everyone's hotel for 2 nights and pay for an activity for all of us in addition to the ceremony and reception. We want to give people enough notice to at least think if they want to go and to give us a good idea on how many rooms we may need to book. He wants to tell people now (3 years out) and I think we should say something next year, maybe send a save the date on our wedding anniversary.
My question is how soon should we let people know and how do we let them know that we will be paying for their accommodations for two nights at the hotel of our choice?
