We sailed on May 28th and did have MTD. We did make reservations each night that we planned on being there....6:30pm. We did not find the "reservations" line to be bad. When we came out.... the lines were. That would have been around 8pm.
Also, I did not notice anyone coughing excessively on our sailing. There were 6 of us. No one got sick. We did not mask. We did avoid over crowded elevators. However, that wasn't a problem. So many elevators. Most of the time it was just us! Happy Sailing!!!!
