Huh? Everything is in that link.
What kind of view are you planning to book? Pool or Garden?
Room 6090 is a pool view on the 6th floor facing the park. As others have said, Room 6090 is the best in the hotel. Room 6058 is also a pool view, but closer to the elevators. The farther you are away from the elevator, the better your view of the park. If 6th floor is not available, then you move down to the 5th floor, because the room numbers are the same across the floors. The first digit of the room number tells you what floor it's on. Club is 7th floor, and their numbers may be different, but going from 6 down to say 3, is probably the same across floors.
3082 and 5078 have a view of the water taxi, therefore, they are considered garden view rooms. 3082 is on the 3rd floor, 5078 is the 5th floor. If you don't get a pool view room, than a view of the water taxi would be your next best bet. After that, your view would be looking out the front of the hotel.
If you want a good view of the park, pool, and not a long walk to the elevator, room 6058, or something close to it would be your best bet. You'll have to call the hotel and ask for your room number in advance, otherwise, they'll just assign you anywhere.
