I am so exciting and can't stop looking forward to have a go

I am so excited and can't stop looking forward to having a good time during the vacation两个错误,第一就是excited,兴奋的。exciting让人兴奋的。第二就是look forward to 后面加动名词。 再问： 现在句意通顺吗，符合表达习惯吗？ 再答： I am so excited and can't stop looking forward to having a good time during the vacation。改成这样就行了，很普通的一句话。
