The park’s entrance is less than impressive, as it’s set on an industrial estate. The park's grounds, though, are well-maintained, with lots of open green spaces and some nicely landscaped areas with fragrant lavender plants. It is a fairly small site compared to other holiday parks, but this could be a bonus for some as it’s quick and easy to get around. The common areas feel relatively new, the reception area colorful and whimsical, the restaurants like chain eateries, and the playgrounds and sports fields well-maintained. Most visitors here are traveling with children and looking for a low-budget vacation with lots of activities. There's always plenty of staff around the site and the lively atmosphere feels convivial and friendly.

Located on the Granby Industrial Estate, Littlesea Holiday Park has little in the immediate area and isn't especially impressive upon arrival. But there is a small nature reserve on-site, and picturesque Chesil Beach is around 15 minutes away on foot, but other attractions are further away. Weymouth town center, with its traditional pier, is a 10-minute drive away, as is the Weymouth train station. Weymouth Sea Life Center is also a 10-minute drive, and Abottsbury Children's Farm is a 15-minute drive. The popular Adventure Wonderland theme park is just under an hour’s drive away. There's plenty of parking at the park.

Accommodation at Littlesea is in trailer-style caravans or safari tents, and campsites are also available for rent. All are decorated simply, with a homey atmosphere and modern appliances. The tents sleep up to five people in two bedrooms and have a wooden veranda, electric lighting, a small dining table and chairs, and a small kitchen area with sink, electric burner, fridge, and microwave. Kitchen utensils, cutlery, and crockery are also included, as is bed linen. Caravans come in a wide range of sizes and comfort levels. They all have a small shower room and kitchen area. The Standard is only heated by a small gas fire in the lounge, and can get cold during the night. Higher-tier options have full central heating, though. Bed linen is not included but can be added for an extra fee. Cleanliness and condition of the caravans seems to vary widely, with some showing signs of mold, dust, and a smell of cigarette smoke. 

The Littlesea Holiday Park has three restaurants, two of which only serve take-away food. Breakfast, lunch, and dinner are served at the park's main restaurant, which offers classic dishes such as pies, burgers, and pasta. The food is fairly expensive though, and items regularly run out. There's also a takeaway fish-and-chip shop, a takeaway pizza place, and a coffee shop. There's a small convenience store on-site, too. The bar hosts regular musical shows, comedy acts, and hosts trivia in the evenings, although it is a small space and it can be difficult to get a seat sometimes.

There is a good range of activities to get involved in, although there’s not quite as much as some larger holiday parks. There are outdoor sports courts and an amusement arcade, as well as four separate kids' clubs, which allows each one to be specially tailored to a specific age group. Parents can stay and join in the activities, or leave the children in the care of the staff. Older children can get involved in nature themed outdoor activities -- the Park’s Rangers run sessions on things like bird-box making and bug hunting. Littlesea also has indoor and outdoor swimming pools; the indoor one was renovated in 2015 and, while it isn't huge, is extremely child-friendly, with features like water sprays and spouts. It can get very busy during peak season, and timed swim sessions are imposed occasionally.
