Did a city break from Glasgow to Belfast, whilst talking to the hotel receptionist she stated that the tour was the best way to see the city, and we could be uplifted from the hotel, 10 minutes later a mini tour bus picked us up and dropped us of at the first stop on the tour route.
The tour is well worth the money, with the added benefit of 48 hour ticket duration and the hop on/off facility at the 20 different locations visited. The tour guides are very knowledgeable with a little bit of humour thrown in. All the locations visited are interesting, we used the tour on 4 different occasions over 2 days.
Easy to recommend to see the city quickly over an hour and a half then go back and visit what you have further interest in.
