We are regular Seabourn travellers but new to Odyssey so comparisons with the 'triplets' are somewhat inevitable. In Feb - March 2010 we cruised from Sydney to Hong Kong via Cairns, Darwin, Bali, Brunei and Kota Kinabalu over 21 days and enjoyed ourselves greatly.
Odyssey is very beautiful but it is not a yacht. Eleven decks, 30,000+ tons, and 450 passengers is not going to be a yacht. On the other hand Odyssey has probably the highest ratio of public space to accommodation of any commercial cruiser afloat. One can see just by looking at Odyssey that much of the accommodation finishes midships leaving vast areas of deck space for lounging, eating, drinking or whatever.
Most the decks aft are open to passengers and provide delightful areas to relax, plunge, soak or whatever you wish. The Odyssey layout ensures that anyone who wants seclusion or privacy can readily find it.
Suite 536 is amidships and furthest aft of Deck 5 accommodation. It is quiet and has no neighbouring door. It is also close enough to the laundromats to save a lot of time without being inconvenienced by therm.
