No, they could not. Considering that a US soldier normally served for 12 months, they were given a one-week Rest and Recuperation leave after six months and were only permitted to visit either nearby destinations such as Thailand and Japan or destinations within South Vietnam itself. There was however one destination that was very popular with married soldiers and that was to spend that one week in Hawaii so that they could reunite with their wife and/or family. This was the closest they could get to where they came from and it was for this reason as to why single men also chose it as their destination over the otherwise more exotic choices that were available to them.
