text: A trip to Europe for most people is a once in a lifetime event and it should be special.  Make it more so by telling her your plans then planning the trip together.  That doesn't prevent you from planning a couple extra surprises during the trip to make it that much more memorable.  Maybe hire violinists to play at a Great restaurant that you have agreed to go. Hire a photographer to follow you around one day.  Order her an outfit from a Paris designer.  I am sure  you can improve on these suggestions.  Have a great time.
