Too expensive
Also, developers ask you to leave a review about the trip and offer money for it. I don’t know if it’s allowed to do this. But this is at least unethical.
Response from developer
Thank you for your feedback! The pricing policy is set by the boat owners. But, judging by the experience of our users, in our application you can find a vacation for any "pocket". Getting an in-app bonus for a review is a regular marketing campaign with benefits for both parties. The shipowner receives feedback from the client and the opportunity to attract new ones, and the client receives a bonus for the next trip.
