At 7 months pregnant (entering the third trimester), you should strictly avoid all high-speed, high-impact rides, including roller coasters and drop towers. Theme parks like Disney World and Universal explicitly post warning signs for expectant mothers on these attractions due to the risk of placental abruption—a medical emergency where the placenta separates from the uterus due to jarring forces or intense G-forces. Furthermore, the restraint systems on thrill rides are not designed to safely accommodate a third-trimester abdomen. However, you can still enjoy many "slow-lane" attractions such as the Carousel, "it's a small world," or the Liberty Square Riverboat. It is also vital to consider the physical toll of walking miles in the heat; at 7 months, many women find that long days in the park lead to significant swelling and fatigue. Always consult your OB-GYN before your trip, and prioritize "chill over thrill" to ensure both your safety and that of the baby.
