I'd give this 3 and a half stars but there are no half stars. This was my first backpacking / solo travel / extended trip experience so of course it was exciting for me at that point! Since then I have travelled lots more, to South East Asia, South America, Australia, starting all of them alone! So now I am a little more of a "seasoned" traveller, and now I think trek america is not something i would do now.
I think if you have never travelled before or never travelled alone before this is quite a good starting point. The problem with these kind of trips are that they are over priced (of course, but if you are just beginning to travel it can be worth paying extra for peace of mind), and it is luck if you are in a group of good people. My group was about 1/3 or 1/2 nice to not bad people, and the rest were just weird/boring/immature which definitely made the trip worse. This is why I dont join group tours anymore because you will never know the people you are forced to be friendly with.
Itinerary - it was decent, the best part was the national parks for sure, west coast is definitely the better side. Monument Valley was cool but it felt unauthentic (pandering to tourists), Florida Keys was really fun and a nice chilled vibe there, Miami was nice but not enough time there. In New Orleans we were booked into a house way over budget, I think it was around $110 each for 2 nights, ridiculous but we had no choice. I recommend the heli over Grand Canyon, Colorado was THE most beautiful place.
I am not a person who doesnt like camping, I have done a 3 day jungle trek staying in huts with no internet and conveniences, I dont think I am too fussy with things. But the camping aspect, whilst sometimes enjoyable, was way too much effort. Perhaps if we stayed in places for a longer time it wouldnt be so inconvenient but putting up tents (sometimes in the dark) and taking them down, whilst also having to go food shopping (laborious), cook/wash up, meant that after a day of sightseeing you were shattered. Sometimes I would rather have just bought a take away pizza or something just so we could chill out a little more (others agreed with me too). Many times the campsites were not close to anything (obviously) so you couldn't go out anywhere at night unless you were in a hostel in a city.
So, generally it was pretty nice and some people would love this experience. But for me, it's not my thing. I am quite an independent person and I don't like going around with a tour guide in certain places like being in a school group.
To make this trip better, obviously they wont decrease the price, but it would definitely be better to stay in places a longer time, the maximum was two days! It is really too much to be packing and unpacking that frequently. I also think they shouldn't cook food every night.
