I had an interview today.....?

in my personal opinion the interview went pretty well. We laughed, chatted, talked about the job & so forth. The job start on June 13th, 2011 & the training class is 5-7 weeks. During the time frame that i'll be in training & had a vacation planned from July 21-24. I did let them know in advance about the vacation & they mention that I may not be able to get off for those day. I let her know if I had to choose btwn the two it would be the job. She also mentioned that they have a training class that will start in September & if I should for any reason refuse to take the job offer in June I would be their most favorable candidate over all the others who apply for the position. At the end of the interview she started that she wanted to interview other candidates before she make a decision. Do you think I have the job?? I kinda feel that I don't because at my last job I found out the same day. Please give me your personal opinion or your experience that you've had in a similar situation. Thank you in advance!
