Hi Elaine - it can be wet in Dec, but good temperature. Slightly dryer Oct/Nov. I've heard Andean Trails are good. If you have the budget, why not get them to organise everything - saves hassle, unless you like winging it when you get there!

Only a certain number of people are allowed on the Inca Trail at any time - so you have to have a slot to walk it. If you're wanting to go this year you're not going to have a choice, all the independent travellers positions will most likely be taken by now, you'll have to shop around for a tour company with places still available. I'd actually suggest you look into alternative trails. The Inca Trail can be quite busy, with each camp site along the route full every day and people queuing to get into the gates of Machu Picchu every morning. This one for example: http://www.worldreviewer.com/travel-guides/trekking/machu-picchu-inn-to-inn/10174/ You could still do that on your own or travel in an organised group if you'd prefer. You DEFINITELY won't be able to 'wing it when you get there'!
