My husband and I were just in the Miami area a couple of weeks ago and saw both the Tut exhibit and the Chihuly exhibit. They are both amazing. You may want to check to see if there are even available tickets to the Tut since we had trouble purchasing ours a month in advance. If you do go, try to go first thing in the morning since that is went it is the most manageable regarding the crowds. This exhibit is much smaller than the one that came through the US in the past, but is still quite beautiful. I don't believe these pieces will ever be leaving Egypt after this tour is over, so maybe that might sway you in that direction. The Chihuly is wonderful. Fairchild Gardens has a special evening showing with special lighting on the pieces Thursday nights from 6-9pm. We went to the evening exhibit and really enjoyed it.
