We have all used an elevator, however, elevators on cruise ships are trying to move a lot of people so following these tips can sure help you manage your time better on your next cruise.
1) Always let the people on the elevator exit first before trying to board the elevator. Pushing just wastes time.
2) Never overload the elevator. Let the full one go and catch the next one.
3) When boarding an elevator, get on no matter which way it is going. When waiting on an elevator push both buttons, then board the first elevator that shows up. There are only a few floors on cruise ships, so getting on one going the wrong way can still take you to your floor promptly.
Just using a little courtesy, will often get you much farther faster. And remember, you can always take a health break and walk the stairs!
