We just returned from our WDW stay, 3/2-3/8. My 1 1/2 yr old niece started throwing up on Tuesday as we had just arrived at T-Rex for dinner, so my SIL and family took her back to their resort(SoG). No sooner did they get into their lobby, my 3 1/2yr old nephew started throwing up and running to the bathroom. In the middle of the night my SIL's husband started throwing up and running to the bathroom all the way through Wednesday Night. on Thursday, my husband(we were staying at the Polynesian) started with the same thing. LUCKILY, myself and my 2 sons DID NOT catch the bug , but we were only 3 out of 11 people that were lucky. Hope this is gone for anyone's upcoming trip. I did not know until looking on the boards today that their is supposedly a stomach virus going around WDW.
