[support] Drupal7 or CodeIgniter fro new website?

[Afan Pasalic]

Hi,
I plan to build website about Rotue 66. And. according to my flow- 
chart, it will be a little bit more then basic site. Basic plot: on  
home page you will have an image (US map, or 8 Route 66 states map)  
with links to select a state.
Once you select a state you will have
	a) list of cities (places) within the state you selected in the order  
they appear on the Route 66 (E.g. Kansas: Galena, Riverton, Baxter  
Springs. The order is from Chicago, IL to Los Angeles, CA)
	b) Google map with needles pointed to the cities within the state
To see Places, you have to select a city from the list or the map.
Once a city is selected a page should show
	a) list of Places in the city in the order they appear on the R66  
(Cicero, IL: Cindy Lyn Motel, Henry;s Drive Inn, Robin Hood Muffler  
Shop, Bunyon's Hot Dogs)
	b) Google map with needles in Places.
Clicking on the Place link on the list or clicking on the needle on  
the map, you will get to the Place page with more info about the  
Place: Name (title), History (body), Thumbnail, Location (geo- 
coordinates), Link to Galery/Photo album, Address. City, State. Zip  
info, etc.

It would be great to have multi-level menu "Places" on Main Manu where  
first level are States, second level Cities within the State you  
rolled-over. And, of course, States (first level) is clickable too and  
will show you page with cities in selected State (List/Google map)

I have two options to do this:
a) using CodeIgniter and have mach more control over it (already know  
how to do that but it's a lot of coding involved)
b) using Drupal7. It's probably much faster and safer but how much  
time I need to build something like this as a newbie with limited  
experience building very simple websites with Drupal 6 and 7 (static  
pages, contact form, forum, blog, and some work using View to show  
News on front page, block and News page)

Any thoughts?

Thanks a lot for any help.
