THIS IS NOT A TOUR! When I book a tour I expect to be in a group, with a tour guide. However, this was only the case on day 3. On day 2 I was all alone. I was picked up from my hotel, they brought me to the boat that goes to Green Island, they gave me a ticket and said here, have fun. The other passengers on the boat who had nothing to do with this tour were mainly families and elderly people, so I did not have anyone to socialize with. Therefore, I really would not recommended this tour if you travel alone.
Also the name 4-day tour is highly misleading, because it really is only a 2-day tour, but I knew that in advance.
Secondly, Enjoy a relaxing day on Green Island sounds great. There are certainly a lot of interesting things to do on the island, such as snorkeling, visiting a crocodile zoo, and taking a semi-submersible boat. However, what they forget to mention is that all these activities COST EXTRA. The only thing included in my trip was the glass-bottom boat tour, which only lasts for half an hour. Paying some extra money wasn't a problem for me, but IF YOU AREN'T WILLING TO PAY EXTRA YOU ARE GOING TO HAVE A REALLY BORING AFTERNOON.
Furthermore, I think the trip is highly overpriced. Especially because I had to book a private hotel room, which I normally never do. The only reason I accepted this, was because I thought it would be group tour. If I had known in advance that it wasn't, then I would have simply booked a shared dorm in a hostel, and booked all activities by myself. I'm sure that that would have been much cheaper and I would have probably met some people in the hostel to socialize with.
All in all, I did have a good time, because the activities were great, but I just wouldn't recommend booking this tour to anyone, because you can easily book all activities yourself, which would probably turn out much cheaper and much more fun.
