Here are some links I love and find useful, I hope you do too.
Sky Scanner – best flight search tool I know.
Lonely Planet Thorn Tree – Lonely Plant is a great place for general travel information, but I love the Thorn Tree, where you can post your question and get great answers from fellow travellers. Or find someone who had the same question and see what answers they received.
Travel Zoo – Travel deals, deals and more deals! I love this site.
Canuck Abroad Forum: A great place for information in getting started in various countries around the world.
London Walks – Great walks, I always learn something new and get to see a new nook or cranny of London.
Time Out London – For finding out what is going on in London Town.
Other sites / Apps I love:
Instagram, is a smartphone App. If you love photography you will love this App. You can post your own photos, add their playful filters to alter the mood, and look through all the amazing photos those around the world have been posting. If you have the App I am YHZgirl. Recently someone created a great web interface for browsing from your computer: http://inkstagram.com/#/users/1532312/photos
Apartment Therapy – Great site for design and style ideas in a smaller space.
Pintrest – A great site for bookmarking visually the things you like/love and find on the web. It is all done on “boards” that you “pin” what you like to. It’s also good fun to see what others are pinning on their boards.
Qype – For reviews of everything. Restaurants, spas, museums, hotels, cafes, shops, all over the world.
