Despite the heavy rain, strong winds, and freezing temperatures, swimming with dolphins was a truly wonderful experience! The staff were very nice, and it was definitely worth the trip – one of the most unforgettable parts of my four-country tour!
Even though it's in my hometown, I'd never been there before, so I went with my boyfriend and it was really great. We took lots of pictures and had a lot of fun.
