3 week Itinerary setup? Too much?

Hi, I just wanted to share my base itinerary (so not too many details mainly just the cities we are going to and how long we are staying in each place.) I want to know if I have too many stops or if I should condense the locations? It is for our honeymoon and i do want to try to see as much as I can but I also don't want it to be too crammed if that makes sense. I will say too that the places where we are staying multiple days will have a rest day or a day that wont really have anything planned. If there's anything I should change or and tips anyone has they would be greatly appreciated!
