I'll be staying at Double Tree by Hilton for a couple of days. Is the area safe for a female to walk out on her own? What's around there? I know there's a slipway complex, is it near the hotel. Also, are there shops like mini marts where I can easily get Bottled Water and snacks around the hotel? Do they accept USD? I'll be there for business and would most probably not venture too far. ANything within 15 mins radius. :p Thanks!
