From 7am to 6pm, thanks to our cheerful guide Eddie, it was so fun and not boring. From the introduction of the landmarks and history we passed by, to the exciting music when we arrived at the spot, to the sense of selecting relaxing music while the travelers were resting, to the professional force in the desert, to taking great photos and videos, and to giving us many tips so that we could move efficiently without wasting time, we were really full and had fun. He took good care of families with children and solo travelers, and answered all our questions about life and photo requests. Thank you for the quiz event, Sydney travel tips, and gifts!! I will add some of my personal thoughts. 1) The coffee at the restaurant/store at the dolphin cruise dock is good. 2) On the dolphin cruise, the dolphins come very close, right under the cruise. I recommend that you do not go up to the second floor, but hold on to the railing at the front of the deck and watch. 3) On windy days, even if the sun is warm, it is cold on the cruise. Bring a windbreaker. (As of early April) 4) If you have long hair, it would be good to bring a comb because it will be messy after being exposed to the wind on the cruise. 5) Sandboarding is not a board you stand on, but a sled you sit on. They tell you to prepare sandals or slippers, but I recommend just taking off your shoes and playing. The sand is fine, so it doesn't hurt and it's not too hot. (As of early April) 6) You'll be in the desert for about an hour, so you'll feel it getting hot in real time, so you'll definitely need to apply sunblock. However, there will be a lot of sand on your face and arms, so it would be better to spray it on rather than applying it like a cream or stick. 7) Don't worry about the photos because the guide takes them so well. It's a matter of personal preference, but I think it looks good to wear slim clothes for both men and women. 8) You can eat sand. People don't just eat sand, they eat phones and bags, so if you start shaking it off, it will come out endlessly. Be prepared. 9) They say it's good to prepare a towel to shake off or wipe the sand. I forgot, but it didn't really matter. 10) You can meet koalas and kangaroos very close at the zoo. You can't hug them, but they feed them and take pictures without any additional fees. 11) Oakvale is not very big, but if you want to walk around every corner, don't sprinkle too much food on the herbivores at the beginning. 12) The lawn is also the animals' toilet. Look carefully and be careful with sandals or slippers.
