moving table-based HTML site to WordPress Easily

I have an HTML-based site full of tables at http://www.home-sweet-mexico.com. I want to “move” this entire site to WordPress so that I can use it as a CMS. I also want to get rid of the tables and use CSS.

I want to keep the text (not the formating) during the move. I’d like to let my theme and CSS do the work of formatting. I’ve tried copying and pasting my pages into NotePad and WordPad, saving them as .txt files, then copying and pasting into the Write/Page screen of WordPress. I’m still getting strange formating.

What is the best, quickest, and Easiest way to move many pages which are on my harddrive as .html files into WordPress? I have around 80 pages, so I need this to be slick.

Thanks in advance for the help.
