Opinions req'd for New York-LA trip

[Sundae]

I am currently considering taking an extra special holiday early next year. The link takes you through to the relevant brochure page of the one I am seriously considering, but in summary:

- A trip with Trek America which involves both hotels & campsites
- 19 days, starting in New York and ending in LA
- 12 nights in hotels, 6 nights at camp sites (in both cases sharing with a member of the same sex)
- All camping equipment provided except sleeping bag (& optional mattress)
- Max tour group 13 people aged 18-38

I don't want to put off planning a holiday, hoping I meet someone this year.
I don't want to go on a package holiday.
And I don't really want to travel alone in a foreign country (even the US).

So by my reckoning this would be a great solution. I would rather GO somewhere, DO something than lie on a beach somewhere, even though I could do it in great luxury for half the price.

This covers a remarkable amount of ground, and at the very least I'd see a lot of the country. I'd appreciate an opinion from "the natives" on the places visited/ whether the trip would be worth it?
