You can use the following credit cards issued both in Peru and abroad.

Credit cards do not support payment in installments.
Cancellation of any reservation already made must be done one day before the trip begins, and an additional amount will be charged.
We must take into account that the city of Cusco is located at more than 3000 meters above sea level, as are several places visited in the tourist package, so it is very possible to suffer from altitude sickness for which it is always necessary to acclimatize for a day and drink coca tea.
The languages spoken are mostly Spanish, but you can hire a guide who speaks English, of course it has an additional cost since it would be a private tour.
