Inkaways ??

Hi guys, I'm planning my first trip to SA, and was wondering if anyone has used Inkaways Tour Operators out of Cusco (www.inkaways.com)? I am trying to book a 4 day tour that includes the Inti Raymi festival and a one day up to Machu Picchu. I'm a little leary since it is so last minute, and they have openings. We're very strapped for time, so it will be a very quick trip this time. Help!! Thanks in advance.

If it is a one day up to MP...ie. train up and back same day... there isn't the hassle of dates like hiking the trail. I presume for the other days they are just packaging together the readily available city and sacred valley tours and tacking on a commission. I can't see anything to be leary of.
