From the RFID Journal's FAQ
What is the read range for a typical RFID tag?

The read range of passive tags (tags without batteries) depends on many factors: the frequency of operation, the power of the reader, interference from metal objects or other RF devices. In general, low-frequency tags are read from a foot or less. High frequency tags are read from about three feet and UHF tags are read from 10 to 20 feet. Where longer ranges are needed, such as for tracking railway cars, active tags use batteries to boost read ranges to 300 feet or more.

Using active tags would make it feasible in the parks. The only reason they don't use active tags in stores and such are the costs involved.
