In Rome all PRM people are welcome: Sistine Chapel or the Colosseum. The Vatican Museums or the Pantheon or the Trevi fountain and all other sites have the section dedicated to Person with Reduced Mobility (PRM).
The only one not accessible Tour is The Roman Forum, too bumpy and big cobblestones.
PRM also don’t pay any ticket inside attractions like the Vatican Museums or the Colosseum and they don’t make any line.
We have a special Minivan for 1 PRM plus 5 people seats , so total of 6 people.
