We had a lovely break at Littlehampton. We have a motorhome and found an excellent Morrisons only about 10mins walk away which was a huge bonus. We were very worried having read the reviews about noise but it was unfounded. Yes you could hear the road and at times the trains but neither was a problem and we are very fussy about noise. The biggest problem we had with the site was that the toilet/shower block was closed for 1.5 hours every morning for cleaning with no alternative toilet. I know COVID was an issue but no toilet was an issue especially if you did not have your own facilities then you could have a problem. All the sites we have visited previously had an alternative. You can walk from the site into town or to the seafront, it is a couple of miles. We rode our bikes and walked both worked well. The local pub The Six Bells was excellent, good value pub food and only a short walk from the site.
