So, we've been given a voucher for a family experience day by some friends as a thank-you, which is really sweet of them.
However, the list of options for that value is pretty limited and doesn't have anything really suitable for us locally.
It does, however, have the option to top it up a bit to something more interesting for the kids, but will now involve paying the difference, plus a train journey for 4 to get there, plus lunch and dinner out, which is going to cost several times the original value.
We'd have been quite happy with a card and a bottle of wine, knowing that I'm sure they'll reciprocate in the future!
