ADwaple is reporting that 2PM and SNSD / Girls' Generation are currently in negotiations with Everland Resorts to do a commercial together for Caribbean Bay Water Park. Here's the full rundown courtesy of jennying?@2ONEDAY.COM:

This year Everland has appointed idol groups SNSD and 2PM as their models for Carribean Bay. The respective companies are currently processing the contract deals, and it has been decided that Yoona and Taecyeon will be the core members of the CF. An associate of Everland stated "The targets of the water park are families and the younger generation", "We will use our big models to promote and fulfill the younger generation's trendy preferences." It has been planned that once the contracts are finalized, they will start to shoot the CF. This advertisement will be for the opening of Carribean Bay, which will be made public at the beginning of May.

I remember fans were jealous when TVXQ / DBSK / Tohoshinki paired up with SNSD / Girls' Generation for Samsung Anycall Haptic and it'll probably be the case here. Yoona and Taecyeon are together a lot, it's going to be interesting to see the interactions between the two groups.
