Are you sure about that?
Disney doesn’t typically include specific work locations in most job postings, especially for front-line service roles (like Lifeguard, Housekeeping, QSF&B, etc...). New hires in these roles don’t typically learn their work location until after onboarding.
There was a post several months ago on some college jobs site (I believe it was for Valencia College) that was recruiting summer Lifeguards specifically for TL. That said, since it was third-party, it could’ve also been an automated post timed to go up in advance of every summer. That’s what happened with a Patina job posting on a third party site several weeks ago that made everyone think Cultural Reps were coming back when in fact they weren’t.
So if Disney posted an ad specific to TL then I’d say it indicates something (which is why they don’t do this). But if it was a third-party site, it’s very possible it was a glitch.
Nothing concrete has been announced on TL. If they did choose to open it in the summer, I’d expect an announcement within the next month, but if I were planning a summer WDW vacation, I wouldn’t bank on it at the moment. Could go either way at this point.
