Change in Travel Plan again

Just discussed with Adeline about the travel itinerary. Due to lack of time and also transport issue, we decided to shortlist the few places we intend to visit, and then work out how best we can fit them into workable schedule. Basically the places include Hanoi (of course), Halong Bay, Sapa and Tam Coc/Hoa Lu. The problem now is will it be too tight to visit them all, and spend too little time in Hanoi and also train ticket issue for day trip to Sapa. I do hope that my friends can help me, as they worked in Hanoi before.

About Adeline, she seems like want to travel in luxury. I think I need to increase the budget already. :)
