Where it’s worth spending rather than cutting corners is on the things that affect your actual comfort: a caravan or lodge with enough bedrooms that nobody’s sharing a room they’d rather not, a park close enough to what you actually want to do that you’re not driving an hour each way, and decent waterproofs and footwear so a bit of British weather doesn’t spoil a day out. Saving money by squeezing into a smaller unit or picking a park purely on price, regardless of location, tends to show up as a less enjoyable week rather than a genuine saving.
Day to day, you’ll be doing your own cooking and washing up, much as you would in a self-catering cottage, so it helps to bring a few kitchen basics like tea towels and washing-up liquid rather than assuming everything will be there. Bedding is usually provided, but it’s worth checking your specific booking, since this varies park to park.

None of these questions take long to ask, and any decent holiday park will have straightforward answers ready. If a question gets dodged or fudged, that’s often more useful information than the answer itself.
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 https://www.thesuffolkcoast.co.uk/where-to-stay-suffolk-coast/caldecott-hall-country-park a car boot cool bag makes packed lunches for day trips much easier.
Footwear deserves more thought than it usually gets. Bring proper walking shoes or trainers for dunes, coastal paths and pebble beaches, sandals for round the caravan and the pool if your park has one, and something you don’t mind getting wet for rockpooling or a paddle. Flip-flops alone rarely survive a full week of coastal walking.
