One of the most difficult things to do is planning for a trip.
However, by being a bit systematic, you can avoid last minute hassles and issues…
The first and most essential things to plan for are Travel and Stay
The first and most important part of any trip the the travel details. You has to book the flight, bus, train tickets, if you is planning to travel by these modes of transport. Else if you are driving or biking, then issues like filling up your tanks, checking air pressure and other essentials need to be taken care of.
When one is flying, especially internationally, checking multiple sites and multiple options would give you the best deals.
Then come the other issues, like having a passport that is valid for atleast 6 months, requirement of a visa, checking whether the passport has enough blank pages. If the county you are visiting needs a visa, then applying for a visa early is always better. There are several countries where visa is either not required for Indians, or visa is granted on arrival. List of some of those countries is here-
Once the issues of travel are out of your way, then plans need to be made for your stay. This is highly personal but for international stay, there are various options. The cheapest are the backpackers inns or hostels operated by Hostelling International, which offer different types of accommodation in various international cities. This accommodation is clean, safe and affordable. The other options are hotels of various classes (stars) that can be booked from sites like Trip Advisor or Expedia.
