Planning for next year, probably May or June. Doing the majority of Ireland as an escorted tour mostly because I don't want to deal with driving or logistics. Here's my tentative plan. Looking for feedback or suggestions as far as feasibility to see and do all this in that amount of time. Thanks in advance.
Fly to Dublin from Windsor (we live in Michigan but this saves us quite a bit of money).
One night in Dublin then join CIE Tour of Ireland, which starts and ends in Dublin. Not exactly sure which tour yet but will be a 7 night south of Ireland tour.
Two more nights in Dublin, at a castle hotel with day trip to Giants Causeway.
Total of 10 nights in Ireland.
Fly to Liverpool for two nights (Hard Days Night Hotel), do Beatles stuff.
Train to London via Cotswolds. Maybe 2 nights in Cotswolds (visit Bleinheim Castle, Stratford upon Avon & Oxford).
4 nights in London, seeing some of the things we missed last time.
Total of 8 nights in England, 18 nights total. Fly to Windsor from London.
