it depends on how their parents feel about it. If their parents let them stay in the hot tub for 30 min. then it's their choice. I would let my kids in for 20-25 min.
All the pools around my house say 5 minutes for any kids under 16. I imagine they are on the safe side though.
Hot tub covers can have long lives if they are cared for properly. Hot tub covers are mostly affected by dirt and sunlight so keep it clean and perhaps put a tarp over it if the hot tub is in direct sunlight.
Of course as long as you dont go in water that is too hot such as the hot tub...but if you swim in 'regular' (luke warm) water then your fine! You can go into the hot tub as well. Your body regulates the heat inside so it will not reach the baby.
Very young children should not be in a hot tub at all, older children can safely be in a hot tub for about 10 minutes. Make sure they drink plenty of fluids before and after going in the tub.
Kids can get scalded by the hot water in the "HOT TUB".
This entirely depends on who they are in relations to each other and why they are in the hot tub. People use swim wear in the hit tub unless they are a couple usually. A father and his daughter - no problem. Enjoying and talking in a hot tub is not creepy or inappropriate. A 50yo who find the minor attractive in a romantic or sexual way should stay away. This is btw the rule for all situations regarding people at 50 and minors age 15yo who find each other romantic and sexually attractive.

THE HOT TUB IS TO RELAX
You use a hot tub cover after the hot tub has cooled off. Using it while your hot tub is still warm can cause your cover to break.
What about "pool chemicals in a hot tub"?
