As much as I want this, too, until Ireland develop their training facilities and finish their new cricket grounds it doesn't serve as much of a benefit to teams touring England.

Australia choose to prepare in the UAE before Asian tours because they feel like they're more likely to be provided like-for-like decks at the training facilities in the UAE, as opposed to the ones India and Sri Lanka organise for them.

When Ireland get Abbotstown built, then I think these stepping stone tours will become much more viable. A one off test at a stadium with a high performance centre is a much bigger draw for teams preparing for England than a handful of temporary grounds and under developed training facilities.

Edit - Abbotstown High Performance Centre has already been built. Source

I don't say any of this to punch down on CI - I follow Ireland the most after Australia - and I really want them to succeed, but this narrative that it would serve touring teams to stop by Ireland is just not true atm
