Never been myself but I've followed this one for years. The problem with places like Lizzie Borden is that once they go full commercial - gift shop, overnight packages, themed events - the original atmosphere gets completely buried under the performance of it all. You're not experiencing the location anymore, you're experiencing someone's product.
That said I've read accounts from people who stayed there that felt genuinely credible, not the usual "ooh I saw a shadow" stuff. The upstairs bedroom especially gets mentioned a lot, which lines up with the history of the site rather than just being theatrical staging.
Anyone here actually done the overnight? I'd be curious whether the investigators who've been there felt the commercial aspect actively interfered with anything they were picking up, or whether the location still has enough residual energy to cut through all the noise. Dorset has some pretty unremarkable tourist-trap ghost sites and a couple that genuinely deliver despite the crowds, so I know it can go either way. Would love to hear from people who've made the trip over.
