Vehicles Booked!

The trip is turning from a dream to a reality - we have now booked both the Harley (H-C Travel) and the Ford Mustang (Rentalcars.com)!!!  Very exciting!  We have also booked a lot of the hotel accommodation too.  I was checking on potential hotels in Chicago (our start point) and discovered that a number of the good value hotels that I had previously shortlisted were full - already!  So, in order to be sure of reserving the hotels in the locations we wanted, I decided to make a start on bookings.  Critical places are those with either limited hotels or in particularly popular locations, for example: Monument Valley, Grand Canyon Village, Santa Fe, Santa Monica and Santa Barbara.
The great thing about sites like Booking.com is that you can make the bookings but you are not required to pay until arrival - and the booking can be cancelled up to 24 hours beforehand.
The trouble is that once you start you don't want to stop!  Frustratingly, it seems you can only book about 11 months in advance, so I am stuck at the moment until the end of September 2014 - I can't do any October bookings yet.
Similarly with flights, you can only book up to 50 weeks in advance and, because our return flight is at the end of  October 2014, we can't book that yet.  Not long now though!
By the way - I came across a great App/ website the other day.  Its called Trip It and it's brilliant for organizing a trip itinerary.  You just forward your booking confirmation emails to your account on the site and it pulls off all the relevant info (booking confirmation reference, times, dates, etc) and creates an itinerary with all the info you need in one place.  It can all be downloaded on to the mobile app so you can have all the info on your phone and you don't have to carry round reams of paper print outs.  Brilliant!
