you have some excellent suggestions above.. but
pls dont forget...

u both
are on honey moon.

most important is privacy, quiet times, ( soft bed ? )
and things that you say
and do...

the background will be there...

best wishes to the new couple.

Option 2 it is !! Though Chiang Mai is too good to miss on your honeymoon :(
else you guys will jus end up travelling a lot !
