I am sure travel agents in Hanoi are able to accommodate your request. However I suggest you join a cruise to Bai tu long bay. All the buses end up at Halong Bay jetty and then bum boat ride to transfer to your Cruise ship (where you will be staying the night). The itinerary of my 2D1N for a group of 14 guest, was on arrival at cruise ship we had lunch and then a short rest before meeting up , hop in bum boat, ride to kayak jetty where we paddle for approx. 20mins to the beach, swim, chill for maybe an hour and kayak back to jetty, to hop in bum boat again to go back to cruise , dinner and activities ( games or squid fishing. The next day, tai chi in the morning if you are an early riser, visit a cave and return to cruise ship, spring roll making activity, and while having lunch cruise ship start sailing towards Halong Bay and last ride on bum boat to the jetty to catch bus back to Hanoi. But for people staying another night, you will be transfer to join groups doing the Cat Ba instead of returning to Halong jetty.
