I plan to visit England in July, flying into London.
From there I plan to go to Holland for a few days, via ferry.
The only one I have found is from Harwick, Stena Line. Do you know of another?
Should I rent a car and use it in Holland or would I be fine without it?
I do plan to rent a car upon my return to England.
Thank you for your advice.
Holland has a fantastic public transport system of trains and buses, plus trams in the 4 biggest cities and Amsterdam/Rotterdam also metro's. Cycling is also a major part of life, so hiring a bike is also easy. If your only there for a few days unless you are going well off the beaten track, i think it's unlikely that you will need to hire a car
From London to Netherlands the Harwich-Hoek v Holland is by far the easiest - is there a reason you want another one or just looking for options? The only other direct ferries to the Netherlands go from much further North. Other than that you have to go via ferries to France or Belgium (or Eurostar) and up by land.
I've done the crossing several times, so if you've got any questions on that or the Netherlands ingeneral, just ask post/post
I do not recommend hiring a car in Amsterdam. Most people walk or bike, as Rich said. In fact, many of the streets/alleys are too narrow for a vehicle to pass through. Besides that, if you ask a local for directions, most will only be able to tell you how to walk/bike/take a tram to where you are going, because that is the perfered method of travel. Also, there are a lot of confusing one-ways, etc. if I don't recall . . . .
