My husband and I stayed in new signature suites and they were lovely. Tons of storage space, the bathroom was bigger than expected. Our butler, Nilesh was the head butler and he exceed our every request past our imagination. The suite was worth every penny. The private hallway was serene, we never heard a door open or close. We had breakfast every morning on our patio (which was very large) with a bottle of champagne with fresh orange juice. The small up charge for in room dining for breakfast was worth the money. Our favorites were the steak and fried eggs and crab cake benedict.
The "beetle" button has been referenced in past reviews- we solved it. It is a button on the inside tub that pumps extra oxygen into the jets. The tub also has very cool LED lighting.
Our room and lots of areas on the ship were quiet creaky. The first night on board we had to use our noise cancelling headphones to sleep and we have no problems sleeping. However, this was resolved very quickly. We were lucky enough to have dinner at the Captain's table with the Chief Engineer and within seconds he was on his cell phone and the problem was solved. They also fixed the divider on the balcony that kept slamming into the lock.
