The park personnel laughed at me . Kati liked the playground , especially the air trampoline ( not pictured ) . Here they are on the zip line . It was well worth the price for the kids ( 15 francs each , which included all of the above attractions ) , but the 17 francs for me was a bit of a rip - off , although I did go on the sledge run with Kati at least 10 times .

Question: Why did Kati seem to enjoy the park ?
Answer: They had a lot of adults around .They had a trampoline .None of the above choices .They had a lot of free things to do .
