Hi, am from India and we are planning christmas vacation in the US. We are planning a road trip from Houston to Las Vegas also covering Grand Canyon on the way. My cousin is based out of Houston. Couple of questions that come to my mind is whether it is safe to travel by road to the above places during winter... we will have a big car which will accomodate 4 adults and 2 kids(11 Yrs & 5 Yrs). Is it safe to travel during winters? What kind of precautions do we need to take? Any kind of road that we need to avoid? Are there enough gas stations and motels on the way? What are the 'Need to see places' on the way? This is the plan that we have
Dec 26: drive to Amarillo (10Hrs), stay that night in camping cabin
Dec 27: drive to Flagstaff (9.5Hrs), stay in log cabin
Dec 28: travel through Grand Canyon, arrive at Las Vegas that night.
Dec 29: enjoy Las Vegas shows until late PM, drive to Anaheim, CA (4.5Hrs)
Dec 30: Disneyland
Dec 31: California Adventure, New Year's celebration at mid night
Jan 1: drive to San Diego (<2Hrs), see Sea World
Jan 2: enjoy San Diego sea coast, fly to NY in late afternoon, stay at NY airport
Jan 3: fly back from NY
I need suggestions on the plans and if we need to alter anything?
