London congestion charge question (probably stupid)

[Ace-T]

I must be a bit thick because I can't find the answer to my Congestion Charge question on the web (or I am asking it in the wrong way)

If I drive into central London on Tuesday, park up in a multi-story car park and not move the car till I drive out again on Friday, how much will I owe in congestion charges?

£10 per day in London=£40?
£10 per day moving about in London=£20?
Any other sum they feel like ripping me off by?

Any help would be much appreciated! Thanks!

(Driving in because it is cheaper/easier than the train and I will barf on a bus.)

PS, if you can recommend a great hotel in the centre that won't break the bank it would be good too!

Should just be the two days, assuming you drive within the times.

Arrive in car park before 7am on Tuesday, leave after 6pm on Friday = £0 CC otherwise £10 per day of actual driving.

Certain areas I.e. crouch end have no parking restrictions which means you can drive park for free and just get a short train journey

Might be a few other areas with no restrictions too...
