if by Singpore travel agent, you will set off at early morning, reach Mersingat noon, then reach Tioman by 2pm or 3pm, no need to stay in Mersing. The rooms on the island are all near the beach (maybe 20meters to 50meters), but some rooms' view will be blocked by other rooms. Bajaya got a resort higher above the beach, need to take bus for 15ming or longer, some people like this place because it's quite and higher, but most people don't because it's far away from the beach.
