3 of us on the tour. Parents in their 40's and a 15 year old. Dutch lad called Tim was the guide. We took the 2 hour 5pm tour. It was a great way to see Malaga. It goes through the town to the cathedral, sees a nice church, up the hill for great views of the city and across the bay, through the port, then follows the beach road and returns to base. On foot, in the heat, that little lot would take all day and not be much fun at all.
You are given a bottle of water and there is a break half way round to rest which might seems unsual, but due to the fact you practically have to stand bolt upright, constantly, your legs do ache after a while. The shorter tour would be advised if you are very unfit.
The Segways are easy to control in a straight line and easy to turn and stop. The only thing to makes it a little tricky is the fact the town section can be rather busy and the locals are not helpful when it comes to giving space (why would they be?).
Tim was a very friendly and helpful nice guy, especially with one of the party who lacked a bit of confidence to start with. I would take the tour again.
