Altogether ~26€, ~45 Min travel time and minimum hassle...
Surely that would save a few bucks...I just think the other thing (just taking a taxi both ways) is less hassle. I guess it comes down to € 30 more or less, and dragging luggage and kids in and out of one means of transportation to another...a personal decision.
But I think by now the OP should have gotten all the facts he needs
