Bovington is pretty easy to visit. I’ve been a Friend/member for a while and entry is free other than for special events such as Tiger Day (there are 2 per year) and Tankfest. If you’re planning a special trip, you’d get a lot out of either of these events (Tiger is Spring and Autumn, Tankfest is early summer). Those events are on the Tank Museum website and you need to get a ticket in advance. Dorchester, Poole or Wareham are really close to Bovington and have hotels and decent places to use as a base to visit other bits of Dorset. Clouds Hill (TE Lawrence’s house) is about a mile away from Bovington. I don’t know about the other sites….
