Have to say Similans is great diving, have done three trips up there and the diving has always been good
1st trip loads of mantas
2nd time whale sharks
3rd time was leopard sharks in abundance
The 4 day trips are good, but if you can get a longer trip they will usually spend more time at richelieu / koh bon / koh tachai which are better spots for the big stuff
If do end up staying in the Patong area on your return to shore then, splash out (well the food is reasonable price but drinks add up) on a meal at the Ban Rim Pa, it is on the clifftop looking out over the sea, book a table with a view for sunset
