It is always polite and respectful to say thank you when declining an offered seat as sometimes this is a rareity. The easiest and shortest way to decline this is to use the conditional and say 'I would prefer/ I would rather stand'. You can always explain that when sat down the children have too much energy to sit still/ it is harder for you when the children are sat down.
