Make the most of your time in the UK by incorporating a tour with your journey to and from the Southampton Cruise Terminal.
I have described the following tours with your disembarkation from the cruise ship as the starting point. They can of course be reversed to provide you with a pre-cruise tour, with a pick-up from Heathrow or your Windsor / Farnborough area hotel. I can easily take 4 people with luggage, but for 5 - 8 people, then I can hire (rent) a 9-seater - great for getting together a small group to share costs. I can accommodate different drop-off hotels making it really convenient and hassle-free for you. Please enquire for prices.
Naturally, I will work within your schedule and devise a tour to return you in good time for your sailing or to catch your onward flight, but should there be unforeseeable traffic delays, I cannot be held liable for missed departures.
