We have used Centenary since it opened as it's location is perfect for us for visiting family. The site planting has matured so much over the years and most of the time the site is very popular. It's a short journey to Milford on Sea with fantastic walks towards Lymington and great views of the Isle of Wight. Christchurch is nearby too. You can park in Somerford at Stewarts Garden centre free all day and enjoy award winning cakes in the cafe one of the best you will find and catch one of the frequent buses into town or Bournemouth just outside next to Sainsburys. Aldi and Lidl are a couple of minutes from there too. Castlepoint has a superb retail park max parking 4 hours with one of the largest M&S stores in the country alongside Next and other major retailers. It's in the New Forest so explore it and yes there are obviously lots of dogs on site and sometimes lots of children too. There is a brand new playground this year near the entrance. There is a lot to like although some free wifi would be nice but you will find Stewarts has excellent wifi and coffee two for one between 9am and 10am Mon to Friday.
