Although unconfirmed, there is already speculation that the Theme Park might be built near or next to a Polaris World resort - see quote below:
"The project could provide over 20,000 jobs, attract three million tourists more a year to the region and fill all the hotels in and around Murcia.
Jesus Samper, the owner of Real Murcia, and Santa Mónica Financial, explained last Tuesday that due to a confidentiality contract he cannot give away any details of the new theme park yet. However, huge speculation over the location is already being generated, and all eyes seem to be on land next to the Polaris World urbanisation near Alhama, which happens to be fairly close to the new airport. It is also next to the Green area of Parque Natural el Carrasco and El Valle, and near the Cartagena-Murcia motorway."

Indeed - good news for Polaris owners and everyone in the Murcia region...
