I did the skywalk tour and Hoover dam tour. No complaints and totally worth it. I planned this trip months ago and very grateful I went with grand adventures not some other big tour company as I saw around us during the trip. Pick up once right on the dot and even though I don't eat McDonalds, breakfast was filling which I recommend. The drive felt a bit long but the conversations our group was having and the fun facts that Ben (tour guide) told us kept us all busy and occupied. The scenery was amazing. The Grand Canyon was more than what I expected when I was reading the description on their website. The views of the Hoover dam was beyond awesome! I went just 3 weeks ago so just FYI during these months it's EXTREMELY HOT. So some sort of hat, shorts, comfy shoes, light shirt, and possible rain jacket is recommended. It did rain pretty hard out there so be prepared and be sure to check out the weather a couple of days in advance. Deff. going back out there with grand adventures during the winter time.
