Please DO NOT base a March sailing on the current situation. If it’s of any use, we are currently sailing this itinerary and in Cozumel today with no cancellations noted. Today was an amazing day spent on the beach with my family. 

I am supposed to sail on the Symphony at the end of Feb, and l am just going to sit and wait.. it is way to early to tell what is going to happen, I plan on waiting a couple more weeks before my final payment is due to decide.  

I think it's too early to make this call. If you go back 3 weeks, there really were no issues. Everything that is going on is really the perfect storm of a much more contagious variant and increased capacity due to the holidays. 
However if you are unable to be flexible and want a guarantee that these things won't affect your sailing, cruising is probably not a good choice at this time. 

@Eli3
If you can imagine the shows could possibly be canceled & your ports of call possibly canceled & still enjoy the sailing without these things then go for it. These last few sailings have been impacted but before that it was pretty much as close to a normal sailing as you could get knowing the protocols & being comfortable enough to follow them. If the $$ you spent on this vacation has you struggling with possible changes as mentioned above, please put it off. 
I feel like we may be out of the woods by then but it's just a gut feeling nothing more. I am also mostly a glass half full kind of person & like @twangsternoted how are you getting there? We were all on the Odyssey last week and had an enjoyable sailing, not what we expected but I have first hand knowledge of how it can be done and how to make the most out of it. 
The truth is we just don't know, it's such a personal decision. Only you know your comfort levels, but if you are looking for a sailing expecting what we were used to close to pre plandemic, I would wait until the warmer months. Be comfortable in your decision, but March may very well look so much different then now. 
I would not cancel a March sailing but I could sit on my balcony and stare at the water for days......and I drive to the Florida ports.

I agree with everyone that it is too early to know how things will be in March. 
That said, I just returned from a cruise to cozumel,  roatan and Costa maya. Everything was open and the excursions went off as normal.  The masking rules weren't always clear, but the ports were otherwise normal.
