i have worked hard for a year, learning web design, and at the same time made lots of good quality websites, mostly travel guides ive made 100 odd of these simple quality websites should I introduce them all at the same time? i dont want google to ban me
You can introduce them at the same time, but don't add Adsense to all at once. Let them build a little traffic and then add Adsense. Without traffic, Adsense won't make you any money at first anyway, and it will help you not appear to be building MFA sites.
Google won't ban you because they want all the revenue they can get, so the more sites you have the better. However in the long run you may find that you can potentially make more money selling products and services as an affiliate rather than earning a few cents per click from Adsense. For instance seeing as you have lots of travel sites, you could think about promoting things like hotels, car rental firms and travel companies as an affiliate.
