Subject: last adult vacation!

My husband and I are expecting our first baby in July and have decided to take one more real vacation before things get more complicated (not in a bad way of course) to travel.

We definately want to go somewhere sunny (we live in Seattle) and are thinking of either Cancun or Miami in april or May. Can anyone tell me if Miami is typically warm/dry in April/May? I did a little research and it seemed that the wettest months were summer. Can I expect the temp to be around 80-85 at least?

Thanks for any advice! Kim, in Seattle
