Apologies re delay in responding, depending what time you arrive we have never found the parking to be an issue.
Metres or vouchers from the hotel itself?
There is parking on the street. It's free at night, and metered parking (relatively cheap) during the day. I think it works out to £4 for the day. You can buy parking passes from the hotel reception. We always parked right in front of the lodge, and never had a problem.
There are usually places out front. Ask for a pass in reception they will advise you.
My sister got the pass from the hotel and never had a problem finding a space fairly near the front of the hotel.
Sorry, we didn't have a car but I'm sure there was some parking on the street outside the hotel. I'd phone them and they will advise.
There are a few dedicated parking spaces in front of the hotel, you just ask them for a pass/ticket thingy, but to date we've never required one and parked in a parking bay.
Enjoy your stay, visit to Glasgow!
There are a few parking places right outside the hotel, you can get a ticket from the hotel, I think they cost £2 or £3 per day.
