At the Hyatt Ziva in Cancun they have a dolphin habitat right next to one of the hotel room blocks. We literally could walk out on to our balcony and see the dolphins.
While this might seem really awesome, it was actually sad. I felt so bad for these animals that were being kept in a tank way too small for them just next to the ocean.
After watching the documentary Blackfish it made me so sad to see this.
