No worries!
Next, we board the 10:10 Garelochhead Coaches route 456 bus service to Feolin Ferry, arriving there at 10:30 on Monday morning.
Two options here: the bus back up the island, and the ferry. In case anyone wants the latter: the connection to the ferry is tight (and comes under the five-minute window, I think); however, it is an advertised connection (there has to be a tight turnaround at Feolin due to tidal speeds) and the ferry would almost certainlly wait for the bus if it were delayed.
