Personally I am finding for a solo at the pre and post stretchers are a bit too expensive. I think I am going to try and plan something myself and possibly be in the same hotel (or close) to where the pre stretcher is in Dublin and possibly to some things that I know I want to see in Ireland.
Also since I am traveling from the West Coast I am going to be completely mixed up when it comes to time zones and such and not sure if I am going to be up to a lot of tours and such.
I just hate paying for stuff that I might not be up to doing with the long travel.
