It was a trip of a lifetime. I highly recommend going for as long as possible. We went for 21 days.
The ship was beautiful, great entertainment, great music . Everyone treated you like you were royalty. The guest services was very helpful especially when I needed a dentist. They set up an appointment and had a taxi waiting to take me to the dentist at the very next port.
I love free style cruising, you can eat when ever you want where ever you want and wearing whatever you want. We also shared a table at meals when we wanted and met some very interesting people.
