The museum was free and that's fantastic and very appreciated but not well executed...the wait was at least 3 to 4 hours long in the hot sun children where frustrated they had us in a snake line with no borders making a line and not enough staff guiding the line... everything was getting way to mixed up lines kept getting in twined with each other making the wait even longer I think if they where to do this again they could consider putting up line barriers to keep the lines in order... it was my birthday and I was looking forward to spending the day here but we left it was just way to hot. On a happy note I have been here many times and love the biodome and all the wonderful surroundings just a beautiful place to go.
