Depends how many stops they have sometimes the coach is waiting at airport for ages so I agree get a taxi if you can afford it, around €60. To be honest the transfers can be anything from an hour to 2.5 but you get to see the island
Its nice in the summer watching the sun rise from the balcony, if you're awake in time of course. Surprised to see Christmas decs up already but I expect the turkey and tinsellers will be arriving soon.
Oh, this is lovely to watch. We also visited Mosta and Mdina glass a few years ago, and so its great to see those places again. Hope you enjoyed your time there.
