Thanks for help. Yes I saw about Soyouz, but there you cannot definitely book, I understand with them there are almost hourly buses so one or the other should be able to get, this is the idea, isn't it?
I also saw somewhere something like Cruz del Sur will bring us till Paracas, while with soyouz we will be on the Panamerican nd we will have to get an extra taxy to reach the town.
If I look at the PeruHop website the Cruz del Sur service become a crap and the best is their service, as I have totally no experience of South America I'm a bit confused.
We simply want to be sure we can go to Paracas in a comfortable way on day 1, sleep over there, visit the Islands on day 2, sleep another night go back to Lima the morning of day 3 , go to airport and fly down to Arequipa.
Any suggestion tips .. is welcome
Cruz del Sur is mostly a company for long distance night busses. For shorter legs and day busses, there are local companies that have frequent departures, often without the need to book. For Pisco (Paracas) and Ica, it is PeruBus (previously named Soyuz).
