The July 17 attacks on the JW Marriott and Ritz-Carlton left nine dead and 53 injured, including Indonesians and foreigners.

Police have yet to identify the perpetrators but suspect Malaysian-born fugitive Noordin Top, who heads a splinter faction of the radical Islamic group Jemaah Islamiah, may have helped plan the attacks.

The Ritz-Carlton already has guests booked to stay on Wednesday night, said hotel spokeswoman Els Ramadhinta.

'We have reviewed everything from the incident and made some adjustments but I can't disclose what the changes are. Hopefully we will get some more bookings soon,' she told Reuters by telephone.

The JW Marriott, which is adjacent to the Ritz-Carlton, will also open on Wednesday.

'We have guests booked for tonight and we also have quite a few future bookings,' said spokeswoman Ina Ilmiaviatta.
