Follow the signs for ultrasound and it'll take you off to the right for maternity ultrasound, it has a sign above but like the other comment, the car park is a nightmare! Sometimes there won't be any spaces available so leave plenty of time to park
Leave loads of time to get there because you might have to drive around a few times, the parking isn’t great there😩
I did one scan at Andover before I requested them all to be moved to Basingstoke. You are allowed to ask if you find it difficult 😀
The car park is tiny! Leave in plenty of time to get a space x
