Legoland at 37 weeks

So tomorrow we are going to legoland for my nephews 4th birthday, we’re all getting passes and my son is super excited. However I’m now getting a little worried about going so far along and all the walking.. I’ll be roughly 45 min to an hour away from my hospital depending on traffic if something did happen. Have any of you mommas done any amusement parks or such this far along?
