Traveling during pregnancy, 28+ weeks

LaShawn
Has anyone traveled during pregnancy before? I am trying to plan our Spring Break trip and kind of need some help. I am a teacher so I have to go on SB when my students go on break and I don't want to take my kiddo out of preschool so I have to stick to scheduled spring break. It's the last two weeks in March! 
I'll be 28/29 weeks at time of travel so from what I've read that means that about 98% of cruises won't let me travel. I really want to go to the beach. I live in Indiana and I've also read I should stay with 300 miles (that's a little more than 6 hours) of home. BORING! I've also read that most airlines won't let me fly that late but they all have their own rules. So anyway was wondering if anyone could share their experiences. Where did you go? How did you travel? And anything else in not thinking to ask...thanks in advance
