Is the concept of Honeymoon foreign to Islam?

Over the recent months, I have a small but significant number of people tell me that going on honeymoon trips is contrary to Islam. They don't cite any references but say that Islam only encourages the couple to spent some alone time and then get back to their regular life. They say going on such trips besides being wasteful expenditure is a form of imitating the disbelievers. Some have suggested that new married couples should be encouraged to go on Umrah rather than some holiday destination. Is there any consensus on this among the contemporary Ulema?
