I only had about 36 hours in Georgetown on the Island of Penang on the west coast of Malaysia. What I find is that when you are on small organised tours and you have limited time, trying to fit in so many sites can be overwhelming (especially in a group of 16) so the limited times seems to revolve around seeing one or two main sites, then eating and/or shopping.
We sure did that. Glorious Asian fusion food courts, Little India, Bargain pants and t shirts, A trip to the Snake temple, a public bus ride – that was about all we fit in. I would like to go back and do some more sightseeing, ride the funicular, eat more food, see the Reclining Buddha and more of the historic houses.
