What stay-cations are available in Ireland this autumn?

Many people are considering booking a weekend away in Ireland, especially after the government confirmed this week that the public health advice in relation to travel will remains as is for the time-being: avoid all unnecessary foreign travel.
A new "stay and spend" initiative was also announced this week as part of the July stimulus package. The initiative aims to encourage people to holiday in Ireland during the off-peak season, to help struggling businesses and tourist destinations which would usually be swamped with visitors.
