I will be visiting with my 25yo daughter at the end of January for a week. I could use some suggestions! I know the weather can be dreadful but we will do our best. What area should we stay in? What have been your favorite places to visit? Should we try to get outside the city too? And, lastly, I could use some restaurant suggestions that are good with celiacs. I appreciate any help!

At the end of January you can still enjoy Dublin, just plan for finishing up sightseeing early in the evenings when it gets dark around 5pm and heading off to the nice warm cosy pubs. Ireland has more coeliacs than anywhere else on the planet, so restaurants here will be very clued in on gluten free options, no need to worry there.

Are you visiting your daughter - who lives in Dublin? or . . . Are you and your daughter visiting Dublin? If the former - in what area does she live?

If you want to explore other parts of Ireland, Rabbies offers some 3 day/2 night small group tours by mini bus. Some are seasonal but a few are offered once a week year round. https://www.rabbies.com/en/ireland-tours/from-dublin.

Paddywagon offers a lot of day tours https://www.paddywagontours.com/tour...rs-from-DUBLIN

Collins is a long established tour company that does day trips by large coach - AFAIK there is only one but it runs daily to Glendalough/Wicklow/Kilkenny/

1Thank you, that is a big relief. So excited to not have to worry about the celiac! If you have a favorite pub would love to hear about it.

Thank you for the suggestions! The buses could really come in handy.
My daughter and I are visiting my other daughter who will be studying there for six weeks. I believe she will be staying on the Drumcondra campus of Dublin City U. Are there hotels near there or would we rather stay more centrally (to more easily sightsee while she's in class) and then meet up with her?

That is in a close in northern suburb -- not really near any attractions other than the Botanic Gardens. There is one hotel -- the Dublin Skylon -- which is practically on the campus so would be very convenient for meeting up with your daughter. It is on a main road so lots and lots of bus service both from DUB and into the city (their website says it is under 10 mins by bus to both DUB and the city centre - but I'd think that may be a tiny bit optimistic)
