Changing dinner time to 8 on day of cruise

[JollyDad]

It’s the day of our cruise on Oasis and we would like to change our dinner time from the first seating at 530 to the later 8:00 pm. dinner.  
 

I assume it’s too late to have my travel agent do this since we board today.  Is this possible and how would we do this?

Go to one of the dining rooms which will be open late afternoon where there will be someone glad to change your time.,

 

On liberty all our shows were at 8 pm first show, 2nd was like 10:15 or 10:30 pm. Every night. Some didnt know to book shows as soon as they boarded and got closed out of the early show.

If you are cruising today, all you can do is go see the Maitre D and see if they can switch you.
