Here's one idea:
• Take the train to Tampa on Saturday, 1 May 2021 ($18 Coach, 2 hour ride on the Silver Star)
• Board the Royal Caribbean Cruise Line ship Brilliance of the Seas for a 5 night cruise to the Cayman Islands and Cozumel Mexico ($1,850 including gratuities) returning to Tampa on Thursday, 6 May 2021
• Then take the train back or Orlando that same day (another $18)
While that total cost for the cruise of $1,850 sounds like a small fortune, here's the way I look at cruise costs. This one works out to $93 per night per person and that includes room & board - all the board you can eat!
There are other cruise ports in Florida, but to me Tampa has the advantage of being able to handle only the smaller ships (due to clearance under one bridge) and the train station is only 1 mile from the boat dock. And if you wanted to play it safe (and daily Silver Star service is restored by then), you could get to Tampa by train a day before the cruise (30 April 2021) and stay overnight in one of the two hotels located between the train station and the boat dock. Let the Amtrak engineer, the cabbie and the ship's Captain do all the driving.
