The keyless experiment was a success. That is the only conclusion to be drawn from the announcement that Starwood Hotels and Resorts is expanding the use of technology that lets guests use their smartphones to open their hotel doors. Connecticut-based Starwood tested the technology at 10 hotels in 2014 and has now expanded it to 130 hotels and resorts in 30 countries. The hotel company said last week that it was installing the technology in select Le Meridien, Westin, Sheraton and Four Points properties over the next few months. To open a hotel room using this technology, guests must be enrolled in the Starwood loyalty program and must download the Starwood Preferred Guest app. The feature is being used most often at its hotels in New York, Chicago, Atlanta, Dallas and Miami.

Site forbids revealing clothes

Visitors who dress immodestly will not be allowed to enter Cambodia’s famed Angkor temple complex, the agency that oversees the site said Thursday.

Long Kosal, a spokesman for Apsara Authority, which oversees the archaeological complex, said that beginning Aug. 4, local and foreign tourists will be required to wear pants or skirts below the knees and shirts that cover their shoulders. Those not dressed appropriately will be required to change their clothes before being allowed to enter the temple site.

Long Kosal said the ban was implemented because “wearing revealing clothes disrespects the temple’s sanctity.” Illustrations of what is considered inappropriate clothing and behavior are being posted on the organization’s website, an English version of which is still under construction.

In 2015 about 2.1 million tourists visited Angkor Wat, spiritual center of the Khmer empire that dominated the region from the ninth to 15th centuries.

Immodest dress is not the worst breach of modesty the temples have suffered. Early last year there was a small spate of Western tourists who posed naked for snapshots, and those who were caught were fined and deported.
