Mike,
Scotland will be fine then in terms of courses and hotels etc, as it was for much of 2020 post June. We just weren't allowing anyone in from the US without the 14-day quarantine.
The UK Transport Secretary announced that from Dec 15 England is reducing quarantine from 14 days to 5 days if you pay for and receive a negative test result in those 5 days. Who knows if Scotland will follow.
Until now our politicians have been pretty conservative with predictions but they are close to unanimous that all will be well by Easter. That is entirely dependent on vaccine rollout which starts next week in the UK as a whole, from next Tuesday in Scotland. For all their mistakes, the UK government seems to have backed enough horses to have 20% of the global supply of the Pfizer vaccine produced before the end of the year, coming to the UK.
You asked for a gut feel and mine is that we will be green light go for the golf season for a multitude of reasons I wont list now. The vaccine news and the already reduced quarantine announcement that came before the vaccine approval are the biggest indicators that we are heading in the right direction.
For the sake of courses, hotels, transportation providers and the wider Scottish/UK/Ireland tourism industry, let's all hope that gut feel is correct.
Simon
