Agreed with the above - when we have a cruise that's pretty far out we just check in about 1x week or so to see what has opened up, at least while > 9 months out. Most of the action in your cruise planner probably won't start in earnest until sometime next year. As you get closer to the sailing, maybe within 6 or 7 months or so, you'll of course want to steadily check the cruise planner more often as things will open up for booking more and more frequently. As you probably know already, there's quite a bit to reserve on Odyssey ahead of time if you'd like to optimize your schedule, from restaurants to production shows to various activities. We were on Odyssey in Europe earlier this summer and found we had no significant trouble getting the times we wanted for various things so long as we planned ahead appropriately. It is a beautiful ship and I hope you enjoy your sailing!

For what it's worth, I made a cruise planner reservation for an embarkation day spa treatment on Odyssey (5/18 sailing) for a certain time, but when I showed up, it had loaded in their system for a totally different time that day. It wasn't a time zone issue or a ship's time/non-ship's time issue; they admitted that it was a recurring technical glitch between the spa and cruise planner that they see on embarkation day from time to time. They didn't have a technician available at my real appointment time, and, because I had made other plans in a carefully-scheduled embarkation day, I couldn't accommodate the random time showing in their system. Worse than not receiving any sort of apology for the situation, over the next few days it also took 3 conversations with the manager to get a refund. tl;dr, from disappointing personal experience, I'd strongly advise against booking embarkation day spa treatments ahead of time.
