We went in with pretty low expectations as we read some really bad reviews on TA. We really wanted to do a little snorkeling trip tho and as all the tours seemed to have the same problems or issues, we booked the one that came cheapest, thanks to our hotel discount, at 2100 baht per person. Our low expectations made that we actually really enjoyed this trip. We got picked up by our driver right on time and brought to the a big covered hall next to the pier where a breakfast buffet was set up. We expected a shabby table with some quick snacks but it was actually a full breakfast with different options. After breakfast, your personal ladyboy/tour guide gives you some information and you are off for a quick picture and on to the boat. Do mind: you have to take off your shoes and don't get them back until you return to the pier. If I would have known I'd quickly bought some diving shoes in the shop at the breakfast hall. Anyway, off to the islands with a 1,5h speedboat trip. The sea was pretty rough and the boat smacked down pretty hard more than a couple of times. I don't get seasick (luckily) but some people really needed the plastic bags that were (thankfully ;) handed out up front. You are packed inside the boat so don't really get to see a lot of the trip; kind of a pity. First stop was island 8 for 1h free time and lunch. We already went snorkeling there and saw some interesting fish which caused us to miss lunch so can't comment on that one. Next to island 9, 40 min snorkeling off the boat. Then to island 4 for the same thing. Afterwards to the overcrowded beach for drinks and 1,5h back to the pier. Here we got coffee and dessert (which was basic but ok).
As all the other reviews say: don't expect a private tour. You are packed in a boat with other tourists and end up on islands with even more tourists. We did see some really nice fishes and a rather large octopus and really enjoyed our guide Gaga who did a pretty good job. The whole thing was well organized and timings were respected during the whole day, which is something we really appreciated. I would certainly advise Fantastic Similan Travel for this tour, just know up front what you are signing up for.
