Just did cycle trip Nov 8-23...what a fabulous time!!!. I am not a cyclist and was worried about being able to do this trip, but it was amazing. The group was large (18) with a mixture of couples and singles all around 25-69 yrs in age.
I did fall off the bike on the first day and ended with a slight sprained wrist and cuts and bruises. 2nd day fell off again lol. Our guide looked after me well. I did ride the bus in places I did not feel comfortable with. Cycling was pretty decent, around 12-15km/hr for most of the group, the faster riders went ahead. Bike teams were fabulous and kept the equipment well looked after, snack foods plentiful. The heat and humidity was incredible, but after 3 days I was fine.
Crossing boarders was easy. Visited many markets along the way and tried Grasshoppers, Silk Worms, Beetles, Snake, Tarantula, Scorpion and many other delicious Asian dishes.
Visiting the Killing Fields, S21, War museum was very eye opening. The home stay was amazing! what a beautiful experience, got to help with dinner prep, beds were comfy, out door shower relaxing.
The only thing I would say is if travelling single it is worth the extra cost to book single supplement. Spending 24/7 with the group is great but its nice to have time alone.
I took the advice of reviews and packed light...took a back pack and carry on and I did fine, you can wash clothes in the sink and it dries quickly or laundry is cheap.
