Have relatives in Guildford, and would like to visit more often. A
cheap day return is £11.50. But looking at megabus.com I can get a
train ticket for Portsmouth which stops at Guildford on the way. Is
there anything stopping me from booking with megabus far in advance
and getting the ticket for £2 return and using it to get to Guildford
and back again? Also how would I explain it to the guide at the ticket
barrier? Many thanks,
