The SYConnect+ day ticket costs £8.20 and covers bus tram and train in the South Yorkshire area.
For a return train ticket Rotherham to Sheffield the cost is £4.20 anytime or £3.50 off peak.( note 2 singles are more expensive)
The tram only day rider is £4.00.
So for using multiple method of transport the SYConnect + is god value but for a single return journey it is more expensive.
