A Wide Beam...
"That fat kid that cannot jump..."
Ok, I'll say no more!
Imagine this scenario by 
$1000 Entertainment Splurge...
London, here we come!
I would hire a wide beam canal boat for hubby and I, with a couple of close friends, for cruising up and down the River Thames and Central London.
Wide beams have engines and are mobile, but you probably guessed it, right?
Wide beams are twice the width of narrowboats; impractical, and unsuitable for navigating and exploring along the narrow canals in England.
However, wide beams are perfect on wide rivers.
So, with $1000, my dream of a weekend in London, exploring museums, live entertainment, and sushi bar-hopping could become a reality.
To Enhance My Weekend Entertainment Splurge:
Away from the hustle and bustle of vibrant Central London, a city that doesn't sleep, we would relax onboard a spacious wide beam, taking in the best of what the city has to offer, from the waterfront.
London is a complete city that holds so much history, with something to see everywhere possible...and no, it would not be fun to visit London with an empty pocket.
Live Entertainment:
According to Wiki, London is the world's third busiest film production centre, so for good vibes, a night on the town to see a live comedy act would be on the cards.
Who doesn't like a good laugh, heh?
Museums
A trip to Madame Tussaud? Oh yay! This would be fun for the group to take photos next to their favourite actors, and celebrities.
Remember, it's not a regular weekend, right?
My palms would be well greased!
Sushi Bar Hopping
London is the perfect spot to experience world-class Sushi Bars outside of Japan.
So, we could visit Soho and Chinatown and eat and drink the finest, of all we can, on my bill.
Don't wake me up from this dream, ok!
Alas, we would spend the final hour on the stern of this hire boat, before going back to our realities.
