1. The main reason is price. Where else can you book accomodation for 6 to 8 people in high season for just over £15.00 per person per night.
In low season it could be as low as £5.00 per person per night.
2. Caravans are not what the use to be they now are like modern flats with all the mod cons, En-Suites, central heating, Double glazing and decks.
3 Most caravan parks are situated in scenic areas of the UK and normally are close to points of interest.
4. Caravan parks have great entertainment for all age groups. Most have kids clubs to keep the kids happy, as if they are happy they will want to come back again.
5. As caravans are self catering you can bring all the food you like to eat.
As you can see the price is attractive, the caravans are attractive, the parks are attractive, the entertainment is attractive what more could you want?
