We boarded Mariner yesterday in Miami. First impressions - the ship is obviously not new, but super clean and no complaints about our concierge suite. I had the best night’s sleep last night, and the first dinner was excellent! Service has been very good too.
Some minor issues - a concierge suite gets 4 wifi devices/log-ins per person but when you upgrade, you only get one. Other devices don’t even get the included wifi, which seems very strange to me. You can switch between devices, but I wish you either got 4 upgraded ones or 1 upgraded and three normal. Another minor grumble is that they are out of the normally stocked scotch I prefer - minor, but as Miami is a provisioning port, I have no idea why they wouldn’t get more.
One last point - if you are tall, try to get a shower stall instead of a bath/shower combo. My spouse is 6’4” and cannot stand up straight in it.
