Dewa Marco
I am in Ubud right now and just concluded a full day of sightseeing with Dewa Marco. Allow me to add my name to the chorus of praise for him. He is everything that other FTers have said about him and then some: responsible, kind, considerate, reasonably priced and very professional. He gives very good value and accommodates all reasonable requests. I don't see how how anyone else can do a better job of showing you the major sights and sometimes hidden points of interest, than Dewa.
