link to dame page from different top menus

hi i would like to link to the same page from 2 different menus. the first menu has pages with cities then places to visit as a submenu. eg sapporo -> places to visit. now i have created a top menu with "sightseeing". i want to be able to create a menu item with just sapporo. when the user clicks on the menu item it should jump to places to visit (for sapporo) i created a page with the title sapporo under the sightseeing menu. then left the page blank and put a Sapporo as the title. this worked to create a menu item with a link to the places to visit sapporo page BUT it also creates a sort of blank menu area just above the sapporo link. if you click this you get sent to the blank sapporo page. could you give me any advice on how to create a menu item that links to a preexisting page. i dont want to create two of the same page if possible, although this would be easy i guess. my test site is at garethrawlins.com. thank you for any help! regards gareth rawlins ps - also im not a programmer i know a little about html though.
