We were on the traditional Sun – Wed cruise Singapore – Langkawi – Phuket – Singapore. You can combine this with a Wed – Fri Singapore – Kuala Lumpur (Port Klang) – Singapore. We (and most other passengers) didn’t do this and I find it a bit strange (also too expensive) to cruise from Singapore to Kuala Lumpur and back. During the weekend SuperStar Virgo is cruising in open water, a tour that is only sold locally, maybe for gamblers.
I can’t comment on any other Ships or cruise hubs of StarCruises. Except that is must be great to depart / arrive on SuperStar Leo at Kowloon Ocean Terminal.
Have fun!
