Do not consider Flash Pack tours as a solo traveler. Their days are strenuous, with 7 a.m. wake-ups, long bus rides, and brief visits to only one attraction daily. The food options were mainly street food tours or low-quality restaurants. We didn't explore historical centers or gain much insight into Vietnam and Cambodia. The itinerary included numerous hikes and bike rides, such as one through a condo development. They prioritize cost-cutting. Hotels were decent, but we stayed in 9 hotels over 13 days and spent only one day in major cities, missing the Royal Palace and historical centers. I was miserable and recommend avoiding Flash Pack tours for solo travelers. Don't waste your money, I know little about Vietnam and Cambodia due to Flash Pack's poor planning.
