I recently had an opportunity to sail in the Grand Panoramic Suite on Oasis of the Seas.  It is one of the finest suites I have ever sailed in. Cabin 1758 category GP is a fairly unique suite.  There are exactly two in the fleet with one on Oasis of the Seas and one on Allure of the Seas.  Later Oasis class ships consumed this space and the similar Owner's Panoramic Suite (OP) on the other side of deck 17 for a larger Coastal Kitchen / Suite Lounge space.   The Owner's Panoramic Suite
