We are thinking of going on an escorted tour to both Peru, for Cuzco and Machu Picchu, and then to Ecuador, for Quito and Galapagos, in May 2013. Could you let me know if you think it is too much to combine these two in a 16 day holiday or whether we should just concentrate on a holiday in Ecuador. Has anyone combined the two and can recommend it; how exhausting was it and did it allow a enough time to acclimatise to the altitude. How many days do you recommend for the Galagos - 5 or 7? Can you recommend any UK tour companies who do this trip? Thanks.
