Sure, it’s acceptable. LBJ and George Bush and Reagan used to spend tons of time at their ranches at all times. There’s nothing sacrosanct about the White House. In fact, DC in the summer is beastly hot and unpleasant. I think this vacation kerfuffle is a made-up controversy. You’re the president 24/7/365 whether you are in California, NJ,. Washington DC, or Hawaii. Saying that 17 days in New Jersey is too long – that’s just whining for the sake of whining. The Mueller investigation is going to continue whether Trump is in Washington or not. The republicans are going to be dysfunctional no matter where the president is.
