Iran tourism boom in 2014 and 2015 and Uppersia advice on traveling to Iran

Iran has experienced a boom in the number of travelers traveling to Iran for 2014 and 2015 and we recommend if you are still hesitant to visit Iran or are not quite sure when to kick off this trip make up your mind as soon as possible and arrange your trip. If you are traveling individually or in small group it is better to book your trip 3 to 9 months before the trip departure but it gets more difficult if you are traveling in big group. Then we recommend to book 6 to 12 moths before your desired departure time otherwise you cannot get proper hotels and services or maybe there wont be any available at all.
The busiest months are Mid-March, April, May, September, October and Mid-November. It would be the best to avoid these months and travel in low season during 2014 and 2015 and if it is inevitable to travel in high season you can arrange it beforehand.
