I'd highly recommend jumping on a party boat cruise.
I did it a couple of years ago with a friend and it was beyond amazing being directly underneath them between the Eye and Big Ben.I think we paid £150 each, but that included tickets, free booze all night, food on board (both a hot and cold buffet) and free VIP entry with 2 drinks to a nightclub on Embankment.
There were two levels to the boat.The upper being a dance floor and lower, a seating area.There was also a viewing 'deck' at the rear. The trip lasted from 8 through to 00:30.Cruised down the Thames to sightsee and turned around at the barrage to get back for the fireworks.
As for hotel, I can't help, as my friend was a squad and we stayed at the Union Jack for a sizeable discount.
On top of all that, the atmosphere was electric.
Hope that helps!
