1. I think the railway sanatorium is better and cleaner. You can take a bath or swim.

2. I haven't been rushed in for a day, but if you don't want to come out at night 10, then say something else.

There is no extra charge for surfing in the spa.

You can play without swimming. If you are afraid, you can hold your swimming ring to surf, but remember to leave the slide and swimming pool quickly after sliding to the finish line, otherwise it will be easily caught by people behind you.
