Airport taxi drop off - holiday inn to avoid charge?

Getting a flight next few days from GLA. Will be carrying a big suitcase so not sure if getting dropped off at BP is feasible. Not been to the holiday inn near the airport, will it be feasible to get dropped there with a big suitcase and does it avoid the charge? Would uber or glasgocabs be better, just an afternoon flight.

Also does anyone know what's a rough cost from West End to the airport via taxi? Took the 77 last time from one of the stops on Dumbarton Road, was thinking of doing it again but afraid of a no show

Edit: any idea about taxi dropping off at the long stay?
