I agree it's probably not an either/or. I have been on Vista. We both didn't care for menu, other than tacos. Reason I made a comparison, is that there is a prior post stating that O's reason for not redoing A & B cabins was a "time" issue. If true, time being spent on adding Aquamar could have been put to better use in A & B cabins.
Friends just returned from 1st O cruise on Vista. Ambassador showed them the "new" Marina....they booked 21 days for 2025. Now cancelling.
Refurbishment on Marina advertised for 2 years and extended once.
