I am going on a 2 month holiday to Europe this year and have quite a few day tours and attractions/activities that I want to book. After going to a few travel agents, prices seem to be much more expensive with agents than online. Can anyone give me some advice on where I can book day trips and 'skip the line' kind of tickets? Viator and get your guide seem great and affordable but reviews are hit and miss.
Any advice would be great!
