Southeast Asia forum

Hi All,
I posted my itinerary a week or so ago and after some very good advice from you have revised it a bit.
I know I am squeezing a bit too much in but is this a bit more realistic? Would appreciate any comments and also advice for accommodation in each place (we are, i presume what they call 'flash packers'). I hear so many different reviews!!!!....

THAILAND (5 days total)
Bangkok (2 days)
Chiang Mai (3 days)

LAOS (6 days total)
Luang Prabang (3 days)
Vientaine (3 days)

CAMBODIA (7 days in total)
Phnom Penh (3 days)
Siem Reap (2 days)
Kampot or Battambang (2 days) any advice here? or leave them out and extra days in PP or SR?

VIETNAM (17 days)
Hanoi (3 days)
Sapa (2 days) - 3 night/2 day tour
Halong Bay [either 1 night/2 day tour OR 2 night/3 day tour] - yet to decide
Hoi An (3 days)
HCMC (3 days)
Phu Quoc Island [need advice on accommodation!!!]
[dependent on what people think we may also want to check out Mekong Delta for a bit...?]

SINGAPORE (3 days)
We fly from Singapore to NZ so want to check it out for a few days....

Have taken out quite a bit from this, like Pakbeng and Nga Trang and Hue.....Left with the basics but think this may be more realistic and more "us". We are keen for a fun place but also keen for chilled out and relaxed.
I know this may be alot but we will fly between a few places or take overnight trains where need be.
I appreciate any advice....
Ta,
Jen
