Start with layers. A coastal breeze can turn a warm afternoon cool within the hour, so pack at least one lightweight waterproof, a jumper or fleece for evenings, and swimwear for the days that do turn properly warm. Even in July and August, an evening walk along the front is usually cooler than you'd expect, so don't leave the extra layer at home on the assumption you won't need it.

If you're travelling with children, pack a beach bag that stays by the door, buckets and spades, a windbreak if you have one, sun cream regardless of the forecast, and a full change of clothes kept in the car rather than the caravan, since sandy, wet children rarely want to walk back for it. Bikes are worth bringing if your park has cycle paths or is close to a coastal trail, and a car boot cool bag makes packed lunches for day trips much easier.

If the park has a clubhouse, pool or entertainment programme, these are usually optional rather than something you're expected to take part in every evening. Plenty of guests use a park purely as a comfortable, well-equipped base and spend most of their time out and about along the coast or countryside nearby, coming back only to sleep, cook and relax.

On the budget side, self-catering works in your favour with a bigger group. Cooking most meals in the caravan rather than eating out as a party of eight or ten keeps costs sensible, and splitting the shopping and cooking between the adults spreads both the effort and the spend. A shared static caravan Tingdene family holiday parks, or two units booked close together, usually works out considerably more cost-effective than the equivalent number of hotel rooms plus regular restaurant bills.

Confirm exactly what's included in your stay versus what costs extra. Bedding, towels, a welcome pack, use of the pool or clubhouse, these vary considerably from park to park and even between different unit types on the same park, so it's worth getting a straight answer before you book rather than after you've paid.

Start with location. Decide whether you want to fall out of your door and onto a beach, or whether you'd rather have a quieter, greener setting with the coast a short drive away. Both suit a staycation well; it's really about what kind of days you want to have. If you like the idea of an early walk before breakfast and a paddle before lunch, a coastal park earns its keep. If you'd rather cycle quiet lanes or potter around a market town, a park a little further inland can work just as well, especially if the coast is only twenty or thirty minutes off.
