Yes my relatives have recently traveled. Protocol are very basic you should have proper details of your stay and COVID negative test should be done prior. You can be quarantined at the place where you are going. Mask is necessary as plus have a sanatizer bottle and wear gloves too ( own safety). And be prepared for any circumstances ( quarantine, flight delay etc.) try to carry compact luggage. Yes you can arrive by cab or by your own vehicle also. No such regulation on that.
