Alcohol makes the fragrance emanate from your skin. Without alcohol, you would be the only person who knew you were wearing any fragrance at all.

Keep all fragrance in a cool, dry area, and away from windows as sunlight can unbalance the various ingredients. An opened bottle should be kept in its box to insure a longer shelf life.

Valentino Perfume by Valentino lasts longer on some people than on others because of differences in our skin (oily or dry) and in our PH levels. To achieve a longer effect, try layering your fragrance. Using the fragrance bath gel, (if the company offers one), then the moisturizer or powder, and then the Eau de Toilette, Eau de Parfum or Eau de Cologne, will usually have a longer lasting effect.

Also, apply your fragrance low on the body, as well as behind your ears and on your neck, so that the scent rises and you won't lose it as quickly. A light spray on the hair can last all day.

There is absolutely no difference in the fragrance. The difference is in the application only. However, a spray bottle, being ostensibly sealed all the time, may actually have a longer shelf life. Making the decision between spray and splash is entirely a matter of personal preference.
