JRT, the answers to your questions are:
1.
Yes - After 14 days you can move on and stay anywhere in Phuket or indeed anywhere in Thailand including Bangkok and Pattaya and you can stay in any accommodation. Additionally,
Phuket 7+7 is now in operation which means that after 7 days in your Phuket SHA+ hotel, you can travel to Ko Lac, Ko Yao Phi Phi, Railay and also Samui, Pha-ngan and Ko Tao for the remaining 7 days of sandbox.
2.
Yes - Visitors are allowed to your SHA+ room. Contrary to common misunderstanding;
you are not in any sort on quarantine in the first 14 days in Phuket. The idea of the SHA+ hotel registration is that 70% of the
staff must be fully vaccinated to help protect them, their families and the local population.
3.
No - Unfortunately all bars, night clubs and massage parlors in Paradise (and everywhere else in Phuket) are still closed at this time. However, there are still many of the staff who worked at these places around in Patong. Zoom-in on Grindr to the Paradise out Soi and you will find a number of guys (Thai and Burmese) who have made Patong their home and would be happy to meet you if you do visit. Hit them up for a chat to find out more about what's going on.
Here's a YouTube from sunset yesterday Saturday 21st Aug showing the beach at the end of the day and the restaurants on Thaweewong Road opening for the evening.
