I've found this rumour on Screamscape, so maybe it's not the hotel thing, after all

.
Busch Entertainment - (2/26/08) Busch Entertainment has announced that they will “announce the most significant news in its history” for their Worlds of Discovery parks at Orlando’s Shamu Stadium this Thursday morning at 11am. A quick check of the new Worlds of Discovery website also shows that this “major announcement” will also be webcast live for everyone to see.
As for what the announcement could be, rumor has it that the announcement is so big that August Busch IV will be coming in to personally make it. For the hype behind this, I have to think back to the last rumor I reported (see below) that Busch was working out a deal to build a Busch Gardens, SeaWorld, Discovery Cove and Aquatica parks in Dubai or elsewhere in the UAE. Funny how that new “Worlds of Discovery” brand name would really seem to fit over just such a project like a perfect resort name. Of course there are some whispers about China as well but those always have to be taken with a grain of skepticism.
(1/17/08) Is Anheuser-Busch looking to expand their US based theme park lineup outside of the country? If the latest rumors are true, Busch could be in negotiations for new park projects in East Asia as well as the UAE. In fact, one particular interesting rumor about their involvement in the UAE claims that proposals may have been on the table for a massive entertainment complex that could consist of a SeaWorld park, a Busch Gardens park, a Discovery Cove park and possibly an Aquatica style waterpark as well. Of course as we reported elsewhere today, things in the UAE may not be as robust as they first seemed as many projects are being cancelled or scaled back, though I would think that there is a good chance some of this rumored concept may still see the light of day, even if it’s just a Discovery Cove park which could fit right in to the high end tourist destination concept over there. (Note: I have not forgotten Busch’s minority ownership in PortAventura in Spain however, but these new rumored deals would be the first time that a Busch Entertainment branded parks would set up shop outside the USA.
