Out of curiosity, what RC ship stops in Progresso?  I just booked a Carnival cruise specifically for the Progresso stop to visit Chichen Itza; I didn't know RC stopped there.

You can keep checking, but Chichen Itza needs a certain amount of hours in port to appear.  

Minimum of 8 hours.  it takes 3 hours to get to and 3 hours back from.  The tour is about 90 minutes with a guide and about 30-45 minutes of free time.  The ferry was waiting for our bus to get us back to the ship.  The ship promptly left a few minutes after the group boarded.  It is a long day!

I was just on Vision 2 weeks ago in the Arabian Sea.  The ship, although showing some age is clean and welcoming.  I personally prefer the larger ships but I did not have any problem relaxing onboard.  Reviews given up to this point will have very little bearing on your cruise since none of them are for yor itinerary and crew has changed since then.  I found the crew very very friendly.  They often were the first to say good morning to you.  Food in the MDR was excellent but the menu seemed to lack a lot of beef options.  Once again, probably due to the ship's location.  There was no lobster night either, but we were told that they do not do that outside of the US and Canada.
 
Go in open-minded and you will have a great time.  She is clean, safe and fun.

My 3 children (12, 16 and 18) and I took our first cruise out of Tampa on Vision in 2015.  We absolutely loved it.  The smaller size made it feel more maneuverable, and there were still plenty of great restaurants and options.  The smaller size impacts the number of tens...since you are going at the holidays, your kids should be able to meet lots of friends if they want to.  Have a great time and enjoy!   Jane

3 teenagers...maybe they'll enjoy the rock wall.

Given the reason for your booking, I think you'll be fine. In addition, the Vision has been updated to have some modern features. You might also enjoy having fewer people onboard as it creates a very different type of cruise.

We cruised on Vision of the Seas out of Tampa in November 2015. The ship was definitely clean and safe, and we found the food in the main dining room to be good, with some items being great. Service in the dining room was excellent. Windjammer was hit or miss for us, but we certainly didn't go hungry. We did not do any of the upcharge options. 
 
It definitely is a smaller ship with less to see/do on the ship, but with a 5 night sailing and your focus on the destination, you should be fine, especially since you are looking for a smaller ship experience.
