Many nationalities are exempt from visas when travelling to Malaysia, but you should check the KLIA (airport) website to be sure.
There are two airports in Kuala Lumpur. The airports are located approximately 40 mins from The Alice Smith School and 55 mins from The Boulevard Hotel. If you select a BUDGET taxi from the airport, the fare to the Boulevard is should be less than RM80 (under USD25) .
When taking a taxi from the airport you will need to pre-pay at the taxi counter. The taxi app Grab works well for getting around the city.
