The 4 day 3 night Machu Picchu tour was great. Has you had more time too see ruins on the way.
The guide was great which lots of information and history. I found this intersing about the inca history. The sites we when too were amazing and very eye opening. Has it was the off season it was less busy at machu picchu. But you have to remember the off season is the wet season. So pack water profs and have dry bags, you will need them.
On my trip it rain for 4 days. Sadly we did see a lot of the amazing views but we knew they were there.
