I think that this is main factor. Tourism activities have to be done far from residence. Tourism is a broad concept. All recreational activities can be used in tourism. But I accept that it is difficult question. İt is like; Does chicken exist from egg or does egg exist from chicken?
For example there is an adventure park in Manavgat/Turkey(www.adventure-park.com.tr). If tourists go there, these activities are tourizm. If I get my students there, these activities are recreation.
According to me; Tourism includes recreational activities. İf local people do these activities, their names are recreation. Sometimes we can analyze seperately.
İf we believe we can change. Sport ıs useful and necessary for everybody, but everybody do not use sport. Can tourism motivate people to sport?
