<human>: Can you provide a brief overview of the text?

First time poster- this may be a stupid question, but haven't seen it addressed before (maybe because I'm making up things to worry about that aren't real issues?)

I'm getting married in March 2016 in the northeast US, and have a lot of friends and family who will be flying in or driving ~3.5 hours.  The hotel where we're holding our reception encouraged me to send out STD's right away so people will book their rooms early, since they fill up pretty quickly (we do get to reserve blocks of rooms, but only in groups of 10, and can only reserve another group of 10 when the original 10 are filled).  Our reception is from noon-5pm, and the ceremony will be at my old church literally right across the street from the hotel (so I would think it would start ~11am, but haven't sat down with the pastor yet to hammer out details).  In light of that, should I put the time of our wedding in the STD, or mention that it will be an a.m. wedding?

If I were a guest and just got a general STD card, I might only think to book a hotel room for the night of the wedding, not the night before, assuming it is likely an afternoon wedding and I'd have time to travel (especially if I were one of the many guests who have a 3.5 hour drive).  Is it okay to say something on the STD like "late morning wedding?" Is it also horrible etiquette to write on the STD something like, "This hotel is really popular this time of year, so book your rooms early."
  
We're also planning to invite a bunch of friends/family to our rehearsal dinner the night before, so maybe I could circumvent adding the time of the ceremony when that's not yet set in stone, but instead handing writing on the STD's of those guests who will be traveling far, something like, "We would love to have you present for both the rehearsal dinner and the wedding- more details to follow!" which might let them know to book a room for the night before.  Is that overkill?  Wait to send out the STDs until I know for sure the ceremony time?  Would love any feedback!
<bot>: having a morning wedding at a hotel where the rooms get booked quickly.  Should I mention on the STDs the time of the wedding so people know to get a room the night before too?
