Srila Prabhupad said " One cannot enter dham just by buying a travel ticket". List below are obstacles to visit dham beyond travel arrangements:

a) One inconvenience may be political. Holy places may suddenly be subject to political division, which can make them difficult or even impossible to visit. What was once part of India later became part of East Pakistan, then Bangla-desh. If there is political dispute between the two countries, we may not be able to cross borders in the name of spiritual pilgrimage. Political divisions can also cause a holy place to become lost. Just as the Ganges sometimes shifts her course, so tracts of land upon which the Lord performed pastimes can become lost to our sight. Perhaps generations from now, the Lord or His pure devotees will again uncover them and pilgrims will be able to visit them for purification.

b) Another inconvenience may be our own inability to travel.

c) Another may be our sense of personal disqualification to enter the mood of a tirtha. Every holy place has an internal reality. We are not always qualified to see it, especially if we remain outsiders to the mood. we must learn to see with eyes of devotion. When Arjuna and his brothers were being taught archery, only Arjuna was able to see nothing but the eye of the target bird. Only he was successful at hitting the target. Similarly, we must learn to see to the heart of a place and not focus only on the externals, the apparent faults or shortcomings according to our estimations. We must see the saintly people living there and see a little of their purpose in serving their holy place. Without that vision, we will always remain outsiders, even in the most spiritually authentic place.Srila Bhaktivinoda Thakura indicates this in his Navadvipa-bhava-taranga. After mentioning Isodyana, which he calls "the Lord's garden," he writes that if anyone visits this place in Navadvipa, he will find only thorns. Still, those with qualified vision will be able to see the Lord's garden through his descriptions of it. No holy place can actually be "seen" without qualified vision.
