Best time of the year for a cruise?

My husband and I are planning to renew our vows next year for our 10 year anniversary of being together (5th year married). But we didn't have a wedding. We ran off and did it which alleviated a lot of stress with both of our families lol. But, we want to renew them on a cruise and count it as our honeymoon since we never had one of those either lol! 
   We're thinking Royal Carribean even though I've always wanted to go on a Disney cruise 😂 (I've never been on a cruise before) we will be 24/25 depending on the time of year we go (: 
  Also, we would depart from Baltimore, MD. So I know that limits our options a little bit but not too much. Thanks in advance!
