Unless you've had both your vaccines (or REALLY want the two new creds) - my advice is to avoid Fantasy Island.
I was HORRIFIED when I saw how the place has been allowed to operate, specifically queue lines with Spinning Racer's queue lined up around the side of the ride and all packed in together as if it was 'the old days'. I was also asked to move in Millennium's station whilst trying to keep a respectful distance from other park guests. Staff are all fully masked up etc. but you can count the guests in masks on your fingers, even on rides where the website claims it to be enforced.
There's signs in queue lines stating 'failure to abide by social distancing rules will result in ejection from the park' but these may as well be written in hieroglyphics for all the attention anyone paid.
I'm no 'Karen' but I admit, I asked to speak to a senior staff member (after voicing my concerns at Millennium, I was told 'I know, it's crap, isn't it...') to suggest measures other parks were taking and point out possible consequences. He turned up (flanked by a guy who looked like a nightclub bouncer) and at first implied that I shouldn't have come on a busy day if I didn't want crowds - he had a fair point, but this was by the by. In the end, I think he elected to humour me and smile and nod politely, but the end result is that I've come away without the Spinning Racer cred. I may go back in the morning, or I might not. Their attitude was very much 'well, we've tried telling them, but what else can we do?'
Happily, after a pleasant meal outside a quiet pub and having checked into my 'apartment' in a pleasant village a good 20 minutes from Skeggy, I'm no longer quite as pissed off...
