While Bhutanese citizens are free to travel abroad, Bhutan is viewed as inaccessible by many foreigners. Another reason for it being an unpopular destination is the cost, which is high for tourists on tighter budgets. Entry is free for citizens of India, Bangladesh, and the Maldives, but all other foreigners are required to sign up with a Bhutanese tour operator and pay around US$250 per day that they stay in the country, though this fee covers most travel, lodging and meal expenses. Bhutan received 37,482 visitor arrivals in 2011, of which 25% were for meetings, incentives, conferencing, and exhibitions.
