Good Site, could be better!
I do use tripadvisor extensively for most of my international vacations and trips. But i don't mostly book through them cause i find a huge price difference. you could get better deals from hotels and other services for your customers. Example when we were in Georgia we wanted to do some food walk and home food sessions and when i checked on trip advisor it seemed very expensive, but when i went there and did it it seemed very inexpensive. You need to engage with locals and get some good deals to make business sense for you. I could try and help in travel and food if you are interested. since we have traveled quiet a bit. You can reach me for more details.
