The Arcadia is a decent enough ship although it is by now (2012) probably in need of a refurbishment. Boarding in Dubai was a reasonably efficient affair, a little slow, but i have experienced much worse.
If you are looking for a ship that is internally stunning to the eye then you may be disappointed. there is no WOW factor, but it is clean and well maintained.
The ports of call made this a worthwhile journey especially if like me you have not been to India, Vietnam, Cambodia, Sri Lanka, Singapore, Malaysia, Japan, Hong Kong, China, etc. Do your own research before departure.
