Dear Sandee,
We are really sorry to hear that you didn't enjoy the experience as you expected.
However, on the High Season, it is normal to have some queue to enter a must-wanted experience like the Pantheon. As a matter of fact, on the very same day, we had more than 300 clients and you are the only one arguing about the line.
This could mean two things:
1) You didn't understand the information provided by us and you had to wait in the wrong line
2) You had to wait a little at the Fast-Track entrance, which is normal during High Season, but you entered before the normal line, where people could wait up to 1 hour before going to the line you had to do.
In a sense, if the line is faster than the other ones it is really a Fast Track, indeed.
Anyway, we hope to welcome you back to Rome and let you enter other monuments in just a few minutes - not in hours, like in normal lines!
Best regards,
1 City Tour
