I went to Rajasthan with Chalo Jaai, and my experience was NOT BAD and NOT VERY GOOD - Overall average.
We can criticize the CHALO JAAI in following basis:
TRAVELERS: If u are above 45, then Chalo Jaai is best for you, as the packages they offer are suited for the age range of 45-75, In our Rajasthan tour, 30 out of 37 people were above 50, and all of them were very happy with everything.
HOTELS: They offered us mixed quality of hotels, what I felt was, when it was stay for only one night, the hotel was good or above average, but while it was for 2 or 3 nights stay, then the quality of hotel were bad or below average.
FOOD: Throughout the tour they served their own cooked food, which me and my wife did not like very much as they were like everyday food u eat at your own home, generally it's Roti, Rice, Daal accompanied with Chicken or Fish, less spicy enough for filling the stomach - and low spices guaranteed that u will not have any stomach trouble :-) and also it's appropriate for the aged persons. We went to local or hotel adjoining restaurants for a change 3-4 days.
TRAVELLING VEHICLES: In Rajasthan they offered us a luxury 2/2 bus without AC, it was above 40 degree outside, but we made the full tour on a Non AC bus, in the first day, the manager asked if we wanted to shift to AC coach, but as most of the tourists were old people, they asked for Non-AC.
AC in Hotels: They offers Non-AC rooms, if u want, u can upgrade to AC for approx extra 300/- per night in most of the hotels.
CONCLUSION: I would suggest the young couple who aims to have a luxury tour, do not go with Chalo Jaai, if you are a middle class traveller and happy with minimum facilities, then u will be very happy, and I have seen most of our elders who are above 45 or 50, they gets happy easily so this company is perfect for them. If your main focus is to see the places and heritages, and do not look around for any luxury, then Chalo Jaai is just perfect.
