Deck 04DECK PLANDeck 4 is where the majority of the cabins start. The Forward ones are balcony cabins. The ones amidships are ocean view cabins with floor-to-ceiling windows however these are obstructed by the lifeboats that are stowed here.Aft of that are more balcony cabins.Deck 05DECK PLANThis deck contains only cabins. As with the previous deck, between the forward and aft elevators, the deck goes in a bit and is narrow. This is designed on purpose to reduce the ships overall weight (which affects the center of gravity and center of buoyancy) allowing her to have a larger height above waterline.Deck 06DECK PLANThis deck is all cabins. The one’s amidships are Signature and Neptune suites.Deck 07DECK PLANThis deck is also more cabins. Amidships are more Signature and Neptune suites as well as two Pinnacle Suites; the largest onboard. Theres also the Neptune lounge amidships. This is a private lounge only for suite guests. ms OosterdamDeck 08DECK PLANThis deck contains the bridge forward and cabins throughout the rest of it.Deck 09DECK PLANThe forward part contains the Spa area. The forward area is the fitness center. At the very front of that is a secret outdoors observation deck that’s right above the bridge. ms Oosterdam ms Oosterdam ms Oosterdam ms OosterdamTowards the end of the spa is the Hydro Pool available by reservation only. ms OosterdamAmidships is the main lido pool. As with Holland America ships, there’s a retractable dome that covers it. ms OosterdamThe aft part contains the Lido Bar. ms Oosterdam ms OosterdamAs well as the Dive-In burger and dog’s shack. ms OosterdamPast that is the Lido Market place. Towards the front of it on starboard, there’s a cornered off area that forms Canaletto, the ships Italian restaurant. ms Oosterdam ms Oosterdam ms OosterdamThe back of the deck is the Sea View Pool and a large sun deck. ms Oosterdam ms OosterdamDeck 10DECK PLANThe very front of the deck is my favorite place onboard, the Crow’s Nest Lounge. Another staple on Holland America ships is the prescience of an observation lounge. Who doesn’t want to spend their days in one of these chairs while sailing through Alaska’s Inside Passage or traversing the St. Lawrence river? ms OosterdamThere’s also the Explorations Central part of the lounge that affords guests the opportunity to learn about the destinations that they will be going to via interactive screens, the library, or guest lecturers. ms Oosterdam ms Oosterdam ms Oosterdam ms OosterdamPast that are a handful of verandah and inside cabins.After the cabins, the deck is all outdoors. The sliding dome that covers the pool takes up much of the midships area. ms OosterdamPast the dome, and tucked into the base of the funnels, is the kids and teen areas. ms OosterdamThe rest of the deck is outdoors as well. ms Oosterdam ms OosterdamDeck 11DECK PLANThe top-most deck is split into two parts, forward and aft.The forward part is then split into two sections. The front part is a public sun and observation deck. Right behind that is a more private area called The Retreat. ms Oosterdam ms Oosterdam ms OosterdamHere you can rent cabanas.The aft part of Deck 11 is the sports court. ms Oosterdam ms OosterdamCABINS ON NEXT PAGE
