I'm going to 2 events in swindon at the end of this month. I'm staying in a hotel in Fleming Way,Swindon Central. I've figured out that both of the venues I need to get to (Level 3,Commercial Way and The WindMill pub,Freshbrooke) are quite easy to get to by bus,from Fleming Way. What I need to know is; how do buses work in Swindon? Is it pay-as-you-board? Or do you need a ticket/pass in advance,similar to an Oyster card,in the London area? I've never been to Swindon before and haven't got a clue!
