The Holy Land cruise was prior to the following transatlantic, so we got a 'good feel' for the Odyssey. We've had 8 cruises on RCCL, 4 of which were transatlantic and 1 transpacific. We sailed Celebrity 10 times, 4 of which were transatlantic. Towards the end of the first cruise, we came down with a mild case of Covid, despite having our shots and 4th booster. We were quarantined in our cabin for 5 days ... thank God we had a double balcony! We were treated well with room service meals off the Dining Room menu, must of which were very good ... just a few times where the food was somewhat cold. We received free wifi and movies during those 5 days. Each day, we were monitored by the medical staff. Our room steward, Mariana, often apologized for not able to come in, but always dumped trash handed out and left new towels frequently. Once free from quarantine, she made sure the room got a deep clean and fumigated. She was wonderful.
Although there are some nice aspects of the ship (some cool hi-tech stuff), it's not laid out well. On decks 4 & 5 (the main traveled decks) there are pinch points that severely reduce flow. There are lots of shops with some pretty high end stuff, especially watches ... they didn't appear to be busy much.
The food overall was pretty good, although we thought the menus weren't 'balanced' well ... some nights had multiple seafood options and other nights none ... not much for shrimp lovers. Veggies with the meal were almost nonexistent, but did have asparagus as the main veggie when offered. The cheesecake and cream brulee weren't up to their usual standards, but the french onion soup rivaled Celebrity, which is saying something, Our waitstaff, Idewa and Robert, both from Indonesia were great. We did buy a Dining package and went to Tempenyaki (good show, food lacked flavor), Wonderland (strange but good and fun), Chops (food quite good, but with all the wood, it gets extremely noisy especially with larger groups), Giovannie's Kitchen (not nearly as good as the old version) and Chef's Table (great food, wine pairings really lacking). The Solarium Bistro provided a nice tasty venue for breakfast and lunch until the transatlantic ... more on that later. Windjammer ... almost always crowded! Made to order stuff ... eggs and stir fry! were almost always very good. The rest ... it's the Windjammer silly.
10320 is a wonderful cabin! We didn't know it had a double balcony, so we had both chairs and lounge chairs!! It's right at the back of the ship, so you're gonna 'get your steps in' each day!
