We're on the Mariner right now and she goes into Drydock at the end of this cruise. Our suite hasn't been renovated yet (except for bed linens) and the service is just as always. They plan to renovate all carpeting, drapes and upholstery by the end of drydock. As mentioned by other posters, renovations are being done at sea in empty suites. Most of the crew will be working on the changes during the drydock time. You should not notice any decrease in service or attitude even the day after drydock.
