I have already asked my TA to get the transfers. Ever the "conservative" (aka tightwad), I am always looking for the bargain. After considering the alternatives; train, dragging luggage then ? from station to ship, and taxi at $$$$$, it looks like the pre cruise 2 day package including transfers and hotel are the bargain at $299 per person.
Princess packages seem to be getting more reasonable as I anticipated London Hotels to be much higher via Princess. Two nights at the Crowne Plaza for $299pp, including breakfasts and transfers doesn't sound too bad. The fact that it's the kids' inheritance money makes it a bargain in my book.
Thanks again and smooth sailing,
