My husband and I are fairly active 68 and 70 year old and want to combine our trips. We know that we are going to do the National Geographic Galapagos cruise and want to do the Machu Picchu on our own schedules (with much help from the boards here and a few local guides). It looks like most people do MP after the Galapagos but we are thinking that it might be good to flip that for us. We know that our energy will be good for Galapagos because we will be so excited to see the wildlife but wonder if MP might be hard physically, and maybe mentally after seeing and do so much in Galapagos. What do you think? We want to do them together because of the obvious location issues of taking two trips from the US.
