The Netherlands is a fantastic place IMO, most people speak good English and you will feel welcome. If you've never really had much experience with international travel, it's ideal and any of the EU countries are. Since you are treated pretty much as a citizen of that country and have rights/protection.
Well, if you are travelling by train in the Netherlands use this site...
www.ns.nl/en
It will give you times and fares. Tickets for trains in the Netherlands are much simpler than the UK, advance fares don't really exist and a single or a day return is pretty much the only options. There is a tutorial on how to use the simple TVMs. Very refreshing in my opinion!

I notice your location is Durham.
There are several ferry options easier than getting down to Harwich in Essex.
DFDS Seaways sail from Newcastle Port to Amsterdam Port. www.dfdsseaways.co.uk for times & offers, plus you can book online.
If your flying there - KLM fly from Durham Tees Valley and Newcastle, although they are pricey. Jet2 offer cheap flights from Leeds/Bradford although that may be too far.
As for hotels - try
www.Hotwire.co.uk - they offer brilliant rates if you are willing to book a "secret hotel" that is revealed after you book, subject to the star rating you book.
Also for named hotels try
www.travelsupermarket.com/c/hotels/ - it compares prices from a variety of websites to get you a cheap deal.
If you need any more help, just ask! I will be happy to respond.
