Good choice for a first jolly. (well, being EGTE based, I would say that)
Flying in the West Country is a doddle, it really is and although Exeter can be a bit tricky to spot when its hazy coming from the east, so long as you spot the estuary and city, the airfield will appear to your right - the blue hangars are probably the first thing you'll see.
ATC are very nice and don't be shy to ask for a QDM if its a bit murky and the sun is setting in your eyes. BHD is the nearest VOR but to be honest, if you feel a bit lost hug the coast around Bridport and you can't miss it. They probably won't be able to hear you much before Blandford Forum 'cos of the hills so I tend to stay with Bournemouth until Bridport.
If you want somewhere to park, give Flightpass a call. I'm not sure what your paying but they
may be able to help. (not sure what the deal is these days). Avgas at EGTE ain't the cheapest, though.
Have fun
