Menu Heirarchy question

My site is growing and I am trying to build easier to manage menus. The problem I have is that when I make a top level menu with seperate sub menus from each top level menu the urls shows the sub level menu as a top level item. I need to make each sub menu appear as if it is attached to the top level for site structure.

For Example I had a menu as below

General
Travel
Spain
Day 1
Day 2
Day 3
China
Day 1
Day 2
Day 3
Peru
Day 1
Day 2
Day 3
Day 4
Photography
Animals
Dogs
Cats
Mice
Buildings
Apartments
Flats
Houses
Famous
Bungalows
People
Men
Woman


When I try to seperate this into seperate menus under a top level menu as below, I lose the correct navigation & how its displayed in the url.



General

Travel menu

Spain

Day 3

Peru

You can see what I mean at my website in the travel menu and photography menus. I want to split the travel menu up so I dont have huge menus. When I try (see the photography menu) the url goes back as if each item is off the top level.
