Hi
I am looking to book a trip in late March/early April for 2 weeks to Vietnam.
I am currently planning to fly into Ho Chi Min City and then get an internal flight to I was just wondering if this is a fairly easy trip for me to organise myself and if this is something that I can do on my own or if it would be better to get a guide to organise all this for us. I guess my question is about how easy it will be to travel around Vietnam on my own and if there are any safety issues.

Independent travel in VN is pretty easy to DIY - no need for professional help. My concern is that 2 weeks is not really enough time to see much at all - VN is larger than it appears to be on those tiny maps!
You should know that road travel here should be approached with caution - it can be rather dangerous (especially on long distant buses). I like to use a mix of travel modes (domestic air is excellent).
Aside from the caution, the Vietnamese people are extremely outgoing and generous. Be sure to book the free student guide services of Hanoikids, Danangkids and Saigonhotpot - they're excellent, and you meet the best of Vietnam! Best advice I can give is to research your trip thoroughly - this is rather important for Vietnam.

Vietnam is beautiful destination, with 2 weeks time, you can arrange to see so many beautiful places from the south of Vietnam ( Sai Gon) to the North ( Ha Noi). If you take internal flight to Ha Noi, you can discover some main tourist attraction. Actually, Vietnam has 3 regions: The North, The Middle and the South. You can take some days Ho Chi Minh ( Destination to visit: Ho Chi Minh, Hoi An- Hue - Ha Noi - Ha Long - Sapa ( 15 days). You will take internal flight to Da Nang from Sai Gon, then flight from Da Nang or Hue to Ha Noi.
