Uttar Pradesh

Yes it is a good Institution for travel and tourism and holds a good brand name. However, placements there are highly dependent on your academics and performance.

If I would rank these two colleges (MNIT and MNNIT) on the basis of campus, hostel life, placements, faculty, and infrastructure, then I would suggest you MNNIT.
As for MNNIT - Allahabad, from what I know from my friends who went there, it's great for someone interested in the core branch as well as the teachers being so supportive for someone pursuing his/her passions.
