Jakarta Concert Trip: Ancol Hotel Safety & City Exploration!

Planning a concert trip to Jakarta and need hotel advice?  I'm heading to a concert in Ancol and worried about safety, especially since I've heard about a nearby red-light district and higher crime rates.  Should I risk staying in Ancol for convenience or brave the post-concert taxi rush and find a hotel closer to the city center?  The trade-off is convenience versus safety and ease of transport after the show. 

My biggest concern is getting back to my hotel late at night (after 11 pm).  How safe are ride-hailing apps like Grab and Gojek for solo female travelers? A 30-minute ride back to a hotel outside Ancol feels a bit risky.  Any recommendations on safe areas and reliable transportation options are greatly appreciated!

Beyond the concert, I'd love to explore Jakarta.  Are there any must-see attractions or hidden gems nearby that are easily accessible and safe for tourists?  All tips and recommendations are welcome. Let's make this Jakarta adventure safe and memorable!
