Not sure if this has been mentioned in here before.. but I've noticed an interesting trend with the Busch Gardens websites lately (and reminded about it today when Facebook let me know BGT changed their web address).
Last year, buschgardens.com existed, but the Tampa and Williamsburg sites redirected to https://seaworldparks.com/buschgardens-tampa/ and https://seaworldparks.com/buschgardens-williamsburg/, respectively. If you visit those links now, you are sent to https://buschgardens.com/tampa/ and https://buschgardens.com/williamsburg/.
They seem to be spending some time on separating the brands out more. It might be nothing, but..
