We are heading to Peru and Ecuador in June and was hoping to get a bit of advice on my itinerary before completely locking it in. My plan is as follows:

We want to visit Cuzco, MP, Puno, Lake Titicaca, Arequipa. In total how many days should I spend on those place? Should I take the flight back to Lima from Arequipa? Will total 6 days be enough?

We also want to visit Ecuador, and Galapagos Island. Is 6 days total be enough?
Any suggestions for travel between Ecuador and Galapagos Island?

The total number of days we on this trip is 16 days.

Day 1 - LIM - CUS (flight)
Day 7 - ARE - LIM (flight)
Day 9 - LIM - GYE
Day 10 - head to Galapagos Island
Day 13 - back to Ecuador
Day 14 - GYE - LIM (flight)

Thanks!
