How about asking, what route should I take from Singapore Hotel in Jurong to Sentosa? How much does a taxi cost?

To get from the Marriott Hotel Singapore Novena (or any other hotel in Singapore) to Sentosa Island, you have several options:

1. Taxi: The driving distance is approximately 15-20 km and takes around 30 minutes depending on traffic conditions. A taxi fare would likely cost between SGD \(25-\)35 (USD 18-25).
   
2. Sentosa Express Monorail: This is a convenient option that directly links the main land to Sentosa Island. The monorail operates from VivoCity shopping mall, which is about a 10-minute drive or USD 15 taxi ride from Novena area. From there, you can take the monorail (SGD $4 per person one-way) and alight at Beach Station.
   
3. Public Bus: You can also take bus number 123 from the vicinity of your hotel. The journey takes around an hour and costs SGD $1.50 per ride. Get off at Sentosa Bus Terminal, then walk about 10-15 minutes to get to most attractions on Sentosa Island.
   
4. Ride-hailing services: If you prefer a more affordable option or would like to share the cost with friends, consider using ride-hailing apps such as Grab (SGD \(8-\)12) or Go-Van (SGD \(10-\)15).
   

Keep in mind that prices may vary depending on traffic, time of day, and other factors.
