Two Days in Dublin Itinerary Help Please

I'll (M40s) be in Dublin in early June with my father-in-law (60s) to see a band at 3Arena. Neither of us have been and there seems to be a lot of good options. I made up an itinerary and wanted to see if it was realistic and/or worthwhile. We're staying at the Shelbourne.

Sunday

• Land around 9am

• Check in around 10am. If we can get an early room, relax until lunch at Meltdown or Green Bench. If not grab breakfast at Tang or Bewley's or Beanhive.

• After eating, walk around Dublin in a rough circle starting at the Little Museum of Dublin and going by Merrion Sq. Park, National Gallery, Trinity College (prob skipping Book of Kells/Long Library), Grafton Street, Molly Malone, George Street Arcade, Dublin Castle/Chester Beatty, Christ Church Cathedral, St. Patrick's/Marsh Library, then either the Teeling Distillery or back to the hotel through Iveagh Gardens. Might stop at Loose Canon, Long Hall, Grogan's or Kehoe's along the way. Prob won't hit all of them, depends on how much energy we have (we kinda old).

• Dinner at the Winding Stair then walk though Temple Bar to hopefully find a less busy/old man pub, one or more of Mulligan's, The Palace Bar, Bowe's Lounge, Auld Dubliner, Merchant's Arch, Stag's Head, but ending at Darky Kelly's for the music

Monday

• Breakfast at the hotel then Kilmainham Gaol at 11am (assuming I get tickets)

• Take a car to L. Mulligan Grocer for lunch

• Another car to Gravediggers/Glasnevin Cemetery (can't eat here unfortunately since no food on Mondays)

• Back to the hotel

• Pre-dinner drinks at O'Donoghue's and/or Toner's near the hotel

• Dinner at Matt the Thresher

• Concert at 3Arena

Tuesday

• On to London for another band

I'm mostly thinking I might have planned too much for Day 1 but since we're just walking around we can skip whatever and head back to the hotel at any point. I don't think we'll bother with the Guinness tour since I've read it's very crowded and a little underwhelming.

Also not sure about the dining options. A lot of the best reviewed places are closed on Sunday and/or Monday (Variety Jones, Spitalfields, Uno Mas, Fumbally, etc.). It would be nice to hit something traditional for dinner one night and something more modern the next, as long as it's good. Etto and Note were also under consideration instead of the Winding Stair or Matt the Thresher. Steakhouses/Indian are out at FIL's request, and we'll get some Chinese in London. Any dining opinions here would be appreciated.

Anything I missed (another museum? a better pub?) that I can add or switch in? It would have been nice to hit the coast but we won't have the time or energy I think. FIL loves talking to people so anything along those lines is great.

Thank you!
