Stayed at centara villas twice in the past few years, great hotel with ye cool bar on the beach- say hello to doung and un, they will get you leathered if that's your thing!
Samui is a stunning island, we hired a scooter last year and went all over the island- I wouldn't recommend it if you've never ridden before but If you have just take your time- theres no such thing as rush hour there.
Have a great time , would love to be going back this year
Ta. The Trip Advisor reviews look very good and I already plan to frequent the Cool Bar given the number of times it's been mentioned on the reviews!!
Regarding the scooter idea, I'll make a judgement call when I'm there and I've seen the riding first-hand. I've ridden bikes (from mopeds through to sportsbikes) for years in all weathers, including some countries that were pretty, er 'dicy', so if it looks unsafe I'll go for a Jeep instead.
I've done 'hot' before (Indian ocean) but this may be a new level of hot. Good job I went for a villa with a private pool just metres from the bedroom then!
Thanks for all the other tips and pointers; all duly noted!
