I would say book a dining package b4 boarding and you will be fine. Expect a regular, rather than Premium cruise, and to get your own drinks. I guess we are used to that on RC, so did not notice the lack that the OP did. As for the tender experience, we got there early, no lines, were on the first tender, only a couple of numbers were called at a time, no issues. It may have been completely different later.
We did not find dirty OV windows, I looked out of them every morning that I went to breakfast- maybe 4 times.
And I did not notice any stains on furniture in my room, Constellation lounge, theatre main floor first third near the front, dining room or OV. I loved my room. We knew we had booked an older ship that missed its refurbish planned during covid.
Of course, we were not in the casino, spa, or the pool areas, and did not have a drink package. And we only turned on the tv to see if the ships had arrived and to confirm ship time.
I do not know how just b4 drydock will affect anything, but we had a wonderful time. I hope you do too!
