I am checking on buses to Aberdeen, in advance of our trip next Spring, as that is where we are spending first few days. I have gathered the airport bus will take us to Buchanan St where we get the Aberdeen bus. My question is, when I l check the schedules, there seem to be several options. There is Megabus, Citylink, Parks of Hamilton ? City link gold. Which one do you take? they all seem to be the same price around £58 for two Is there a non-stop bus does anyone know? And would it be necessary to book this before we come. Thanks for your help.
