Update since trip- I personally would not recommend Disney Port Adventure G81 Intimate Trip to Stingray and Starfish based on our experience. We had fun but do not feel it was worth for the price we paid.
Based on price, I had high expectations and expected a small group as described. Maybe my expectations were too high, but based on other Port Adventure experiences I have rarely been disappointed. Most similar excursions I researched had 20-30 passengers, so had I hoped at most 12 but realistically planned for less than 20. Our group was extremely large for being “intimate“. We had 67 total and we were broken down to 3 boats, leaving 24 on our boat. To skip ahead, our boat also broke down on way back, causing us to combine boats on that leg making even less “intimate”.
The sting ray experience was fun seeing them in the wild, however our tour guides were rough handling them, they did not provide a lot of information, and just wanted to group families for the pictures they took. They were also adamant that I could not stand off to side of or behind them to take my own pics at same time. Other tour groups provided food to feed the rays and gave education while this tour did not. I found myself listening in on the guides next to us, which was pretty easy since the site was so crowded overall.
The trip to Starfish Point was the most disappointing. We were directed to the food to go over and get in line for and told to find a spot to sit down and eat. we had options for chicken curry or stewed chicken. In our party the kids got stewed and adults got curry so we could share and try both. All of the plates were nothing but chopped up bones in a portion the size of a side dish, dried out Kraft Mac and cheese, and a large portion of rice. Every bite I tried had a small bone shard and we couldn’t eat. Especially worrisome to provide this to children. After this, we did not interact with our guides again until called to head back. Again other tour guides were interacting with guests taking photos and educating on the starfish. I listened in nearby again to learn. It was a beautiful area, but still a bit crowded with other tour groups.
From here, this is were the boat broke down. All groups left and our boat wouldn’t start. I understand things happen, but after they tried for a bit to get working without success, we had to wait for another boat to come back to get us and it was already loaded with passengers. We ended up getting back to port late and were the last tender. We became “those people“ that were late and looked like we weren’t going to make it despite being booked with disney

.
We still had fun, and others may not have the same issue, but I personally would not book again or recommend for the the price and experience we had.
