Congratulations and condolences too! In 2005 we ordered a brand new caravan and a Disco to tow it. Within days of the order being placed we too received similar good news. By 2014 it was all just sitting in storage and going nowhere so we sold everything. Last Autumn we decided that things were improving and bought another caravan and all the kit too. But it was an emotional purchase rather than an an objective one, so we have now just bought a more conventional caravan with 5 berth!! We can see the light at the end of the tunnel as our last grandchild is a tweenie, but still very keen to go with us. Funny though that I have managed to agree dates and booking etc for the school holidays, at enormous cost, but cannot get my daughter's boss to approve her leave such that we can go solo on our planned breaks. We have been caravanning with grand kids now for 23 +years, yet with our own kids we never took them during main school holidays or half terms as everywhere was too crowded and expensive, even then.
Seriously though you will love it and how nice to have someone doing the domestics chores (except loo) while you can sit and drink nice beer.
