The thing to do with the beach is head towards it and then if you don't make it don't worry, just settle where you are and play in the sand, or you can drive to a number of beaches, the walk there is lovely.
There will be other kids about so they'll have fun with them and we'll do a few activities for the kids as well, the thing to keep in mind is that if you're willing to sacrifice your time to be with them then they'll be happy and you'll be relaxed. Some of this depends on the weather, if it's dry then they play a lot outside, if it's wet...they play a lot outside
They also need more covered space which there's usually enough of, mud maps, plant pictures etc can all be played wtih and there's showers so you can get the kids clean.
