In the calendar year 2010 Bermuda recorded the lowest number of air visitors in 30 years, but had one of the best years ever for cruise ship visitors. Cruise arrivals accounted for 60 percent of Bermuda's visitors in 2010. Air arrivals fell 1.5 percent compared to 2009, which had previously been the worst year on record. In total, 232,262 people flew to the Island in 2010. 61% came on holiday (vacation); others were on business or to visit friends and family. Despite the drop in air arrivals Bermuda's peak season, May to August, had improved compared to 2009. 4,000 fewer people flew to the Island in September 2010 compared to 2009. It was the third lowest September arrivals figure in ten years. While air visitation was down in 2010, these visitors stayed longer on Island. The average length of stay for the year increased to 6.21 nights, up from 6.09 nights in 2009. In 2010, the Bermuda Hotel Association reported it had an overall occupancy level of 54 percent. Only 2001 and 2009 saw lower occupancy levels at hotels this decade. Cruise arrivals accounted for the majority of visitors on the Island in 2010. In total, 585,266 people visited Bermuda, one of the highest arrivals figures in the Island's history. Only five other years surpass the total arrival figure. Cruise and yachts brought 353,009 of those visitors, accounting for 60 percent of total visitors. Cruise arrivals to the island increased for the year to the tune of just over nine percent. This is a direct result of the additional 14 cruise ship calls for the period. In 2011 cruise arrivals are projected to continue to rise. The number of people arriving by cruise this year was the second highest figure in 30 years. Thirty years ago 99,602 people came to Bermuda by cruise.
