We are flying from Kota Kinabalu to Lahad Datu, then back to Kota (and then on to Kuala Lumpur). The flight is less than one hour, then the transfer to the hotel is another two hours.

There is a direct flight from Tawau to Kuala Lumpur, but the hotel says we would need to take a taxi from Lahad Datu, so that route unfortunately doesn't make sense for us.
