My wife and I will be traveling to Rome for 3 days next summer and are looking to jam as much as we can can in those days, hitting all the major big tourist attractions for first timers. I had read about the Rome Pass and planned on getting that when we arrived to Rome. I now stumbled across the "OMNIA Pass" which is more expensive (90 Euros compared to 34 Euros for the Roma Pass). I am wondering if paying that much extra for the Omnia card is worth it? Or if you think we would just be better off getting the Roma Pass.
Also, if I buy the Roma Pass ahead of time, how does it work for me to active the card? Since I think it only works for the 3 days. When I use it then it knows its activated or do I have to pre-register the days I will be using it when I purchase the card. Thanks!
