We just came back a bit over a week ago from Peru. Agreed on all the Sacred Valley highlights mentioned above - Maras, Moray, and Ollantaytambo were definitely our favorites. And MIL is a must do - amazing experience. We skipped Lima this time but adecided that we want to come back to Peru some time just to try out Central because we were so impressed by MIL. On a side note, the F&B manager at Explora mentioned that they signed Virgilio Martinez as their consultant in January and they'll be working with him to introduce a new menu in February. I thought the food at Explora was already very good so am curious to see what they can accomplish!
