Geführte Tour durch den Markusdom mit Gondelfahrt in Venedig

First of all, it should be mentioned that you have to be covered up to enter the basilica when accompanied by a guide (because the other tourists didn't get any comments despite their shorts). That would avoid having to buy a scarf at the activity stand, and the guide wasn't very pleasant - I think there are different ways of putting it! Then it should also be mentioned that the activity lasts about 2h but not to follow! I had an appointment at 10:00 a.m. I thought I'd finish at 12:00 p.m. as registered... But no because the gondola tour (which doesn't even last 30 min) is at 3 or 5 pm !!! I think the whole thing is a rip-off, and if I had any advice to give, it would be to do things yourself, because it's not worth it at all... A gondola ride costs 90 euros in Venice for 1 to 5 people and entrance to the basilica 15 euros. You can take audio guides at the entrance...
