When I went to the Universal's website the single day tickets for park to park start at $165.00. 1- park tickets start at $110.00. I say start at because you can add things to the ticket like line pass and passes for dining plans and such. I found when I went there was a place that you could purchase a refillable bottle and the refills on the drinks were .88 cents after that. That was a few years ago and I am not sure if that is still the case, but it saved us a ton. The drinks and things are expensive. Also, if you are a Florida resident, there is special prices for residents of Florida for purchasing tickets.
$165. Per person per day for park to park $110. For only one park, it may vary if decide for 2 or 3 days and childrens etc. Check site for details.
I would have a look at Prof Steve Keens work
My wife got one park on cyber Monday for $45
