The package tickets for the sea resort at Kansai Airport, 2550 yen including one-day subway tickets and bus tickets for one-day tour in Osaka, are really cost-effective, because this ticket is 800 yen (weekdays) and 600 yen (weekends). The ticket for the sea resort is 2200 yen. There are many sea creatures to watch in the sea resort, such as dolphins, beavers, penguins, and all kinds of fish living in the water. Jellyfish and so on really make people feel back to their childhood, to wonder, to observe, to marvel, to touch marine life... This viewing activity is very suitable for taking children and the elderly to play together. It's very interesting.
