Elevator system on the Horizon was HORRIABLE. We took the stairs most of our cruise. They also need to have a separate elevator for the handicap and scooters. my mother had to spend most of her time in the room because of the lack of working elevators on the ship.Our stateroom was only cleaned once day after asking for twice a day am/pm. Food was not that great. Mike the cruise director was excellent he made the ship experience a little better. Also they need to start breakfast at 6am instead of 7:30 some folks get up early. Guest services employees need to be a little more friendly to there guest and not have attitudes. I have cruised on Carnival several times this was the worst. I do plan on crusing again on carnival to give them another chance and if no improvement I will be going on another ship..
