Looking for places where you can go on weekend(s) with kids , drop them off at a crèche and a have time to relax.
I know some gym networks offer crèche (David Lloyds, for example), there are also spa centres, but these options seem quite expensive.
There are free play sessions at IKEA, on the other hand, but they don't take 2yo and in principle it's very hard to catch a free space there.
Is there something in between, let's say no more than £100 for 3 kids and 2 adults? Something for a few hours. Adults don't need spa treatment
