Conception and vacation

My hubby and I are about to start ttc. We've been "careful" because we have a family trip to Disney coming up. According to all my cycle info and personal tracking of it. We could conceive during the beginning of our trip. My question is riding the rides safe? With my first I was water skiing and playing on the lake at 5 weeks because I didn't know I was pregnant and didn't think to test til we got home. This time around we are planning it and want to be sure baby is safe & I can still enjoy our expensive Disney trip!
