Not always. All tourists visiting religious places may not be the pilgrims. Some tourists are inquisitive about the mythological, historical and architectural importance of the religious places.
Not necessarily and rather not from my experience - I have traveled a lot-; Unless it is a Sanctuary or religious or special cult site and that generates great devotion among the believers of said specific Religion (for example, the Hermitage of the Virgen del Rocío Almonte -Huelva, Andalusia, Spain that has little artistic value but it treasures and generates a great devotion in the Christians, with a massive Pilgrimage or Pilgrimage annually; and, what about Mecca, for the Muslims?); Except for places like those mentioned -and there are thousands- the majority, with great artistic and / or historical value, the interest is usually cultural ... in fact they are visited by thousands of people who do not believe in any Religion or who do not belong, yet being believers, to the Religion to which such Historic and / or Cultural Shrine / Monument is consecrated; Now, even if you are not a believer or of that Religion, it is clear that YOU HAVE TO KEEP THE DUE RESPECT AND RIGHT THAT A RELIGIOUS SITE DEMANDS, FOR THE MOST ELEMENTARY EDUCATION, AND THE RESPECT THAT THOSE WHO DO ARE OF SUCH RELIGION DESERVE !!
Since your question is about RELIGIOUS tourists visiting religious sites, I would say that for the most part, they would be visiting these sites for religious reasons. Otherwise, why would they make all that effort in terms of travel, expense, and time to make such a special visit? My experience in visiting religious sites, such as my recent pilgrimage to Medjugorje in Bosnia Herzegovina in 2019, is that 99% of the religious tourists at these sites come with the very specific purpose of growing in holiness and/or to ask for a special favor of God, such as physical healing for themselves or their loved ones. If your question was phrased without the qualifier "religious" in front of tourist, then I would agree to some extent with the other commentators.
I have tried to complete the Questionnaire that you have kindly sent us, but I could not complete it due to my own predisposition, since most of the time I was not reflected in your opinions. I respect for those who are fearful of exemption from hell's fine and hypocrisy. Just seeing an ancestral religious temple will improve my knowledge, but at the same time I do not seek pleasure, and I do not seek love because it enters a different order of things for me. The religious temple can make me feel the beauty of the experience and the feeling of humility that can emanate from MY SOUL, but it does not have to improve my self-realization. I do not seek individual purification or pleasure in my sightseeing, nor do I seek spiritual pilgrimage, unless I specifically want it to obtain Indulgences, but no longer with the visit of a single Temple but more. If it is a tourist visit, I cannot think of it as feeling of purification, repentance and spiritual renewal, in my tourist visit I look for its Historical value, its lordship, its historical-architectural importance, its aesthetic beauty, and if to this are added legends, memories or interesting stories about the Religious Temple still best.
I believe there are several things you could do with your questionnaire:
1. You have a duplicated question,
2. You have income in Rupies but you may want to add the USD equivalence for foreigners.
3. You should ask for country of residence, religion affiliation and whether they do religious travel or simply intend do do it.
4. Some of your questions should be rephrased so it is meaningful for Christians, Muslims and Hinduists and perhaps another relevant religion on your country..
I guess when you visit a new place you are curious about all of the cities well-known landmarks including the religious relics. However, when I am a tourist in another city, honestly, religious monuments never enter my mind. My spouse and I usually looks for the city's library. I don't know why but we are always curious about what does the library looks like.
