Ms. Ishikawa's introduction was incredibly detailed, and having a Chinese-speaking guide was a huge plus! Ms. Ishikawa took great care of everyone and immediately remembered everyone's faces in the group, which was amazing! The overall experience was excellent. Although we only had 30 minutes at Manzamo and Kouri Island, which might be a bit short for those who love taking photos and exploring, it really tested our time management skills. We had a good amount of time at the Churaumi Aquarium. If you want to take your time looking at everything inside, it might still not be enough, but seeing the enormous whale sharks alone made it worthwhile! There's also a dolphin show, opportunities to take photos with dolphins (limited to 15 groups), and even feed them (also limited groups, very popular, so if you want to do it, you need to line up right after the show)! At the Churaumi Aquarium, Ms. Ishikawa gave a very detailed explanation of the aquarium's layout and facilities, and she reminded everyone not to take a wrong turn, or they might get lost! There are three souvenir shops, and they each sell slightly different items. If you see something you like, it's best to buy it right away, because what's available in shop A might not be in shop B, and vice versa! This was my first time booking a one-day tour, and I really enjoyed it! It was very much worth it. Highly recommend!
