I'm going to be greedy/cheeky and have 2 dream dates (I just couldn’t decide!).
DREAM DATE 1
My date and I both love the US, particularly Portland, Oregon. So first date would start in the US with a morning hike (say 10 miles) stopping at various points for treats, views, etc. Lunch would be wherever the best Philly steak with fries is served, then race and ride dune buggies in the Oregon dunes national park, afterwards take a romantic stroll along the coast (I would be collecting driftwood) and then find the most amazing camp site, with a camp fire going while I put my feet up and relax....while dinner was being prepared (cooked of course by my lovely date).
DREAM DATE 2
If in the UK, then the date wound start in the Lake District with paint balling, lunch would be at the Lakeland café, depending on mood and energy levels (either do one or all three activities) we head off to the driving range, game of tennis or go to a swing patrol dance class....dinner would be at my favourite Italian restaurant, evening would end either at the ballet or the theatre watching a classic play (and if allowed we would like to enjoy our triple chocolate sundae as we watch).
Bliss!
