Shopping in Bournemouth town centre isn’t the greatest!
There are a few large department stores in town, and a reasonable selection of smaller stores.
Poole town centre is split into an old & new town. The old town is very lovely and set around the quay. There’s lots of restaurants and cafes there. The shopping there is limited. There are larger stores in the newer part of town.
Theres a shopping centre about 20 minutes by car thats a little better, Castlepoint. Traffic can be heavy in & out of the centre at the end of the day. Its quite a nice shopping centre though, with a big M&S in the centre, and large Next, Asda, Topshop, Monsoon & Boots stores amongst some of the retail outlets.
