Has anyone heard of Exotissimo before? Did anyone use this agency before? They can do customized itinerary and are reasonable for travels pretty much all over South East Asia. Any comments or opinions?

They are arguably the BEST and most REPUTABLE Tour-Operator you can find anywhere in Asia (and with 16 offices dotted all over the continent)

not cheap, but excellent quality. If you use them, you are on the safe side for sure.

their Main office is at Zuellig-House in SILOM ( a bit odd that they are obviously unable to write the address of their own headquarter properly, as they write ZUELING on their website) but that should not scare you away....

check their website to find out more.

Yes, they have been around for a long time and have a good reputation. But they sure ain't cheap.

" they have been around for a long time and have a good reputation."

Second that; used them years ago and they were good then - not tried them recently.

Ditto...they have been around for some time.

Seem to remember using them once (cant remember why)about 20 odd years when they had a shop/office down by Nana Plaza...bit quiter then...the plaza that is .

Agreed, they're quoite good if you're willing to pay the price...
