Seaworld left me feeling a little uneasy - is it a theme park or a conservation/rehabilitation park? There's loud music piped everywhere round the park which must be stressful for the animals and so much general noise from rides and other attractions. Before we went, I was hoping the animal enclosures would be in a different part of the park, but no.
Some of the staff really didn't care - the lady on the meal deal kiosk near the entrance initially gave my 11 year olds children's meal wristbands (for ages 3-9) even though moments before she'd scanned their adult tickets, and blatantly told us they were the same meal deal as ours (even though a different color). When I asked another member of staff she told us they were the children's deal and changed them for the adult bands!
At the pretzel kitchen, we waited for 15 minutes for a member of staff (Gloria) to refill the hot chocolate machine only to find she'd left the pretzel shop and gone next door to the sweet shop without telling us! When I told her we'd been waiting for her, she wasn't the least bothered.
There were some staff who were happy, helpful and wanted to be there and they made such a difference.
Overall, my kids had a fantastic day and loved the rides and the animal enclosures.
