I kept a log with air prices for ie 2011 that gave me an idea of roughly what the prices might be for the following year. Then when 2012 prices comes out you will know if it is a good price.

We went to London 2x before cruises. The first year, I bought the London Travel Pass with travel. We used it for some of the attractions but I didn't think we got our moneys worth as you can only do so much in a day. It did save time lining up at some attractions ie: Tower of London. We did use the travel portion for the city buses. I bought this online.
We did do the Hop On/Hop Off (HO/HO) bus. Both bus lines have the same routes. The tickets are good for a 24 hour period. They have 3 routes. Can get off/on as many times as you want, they have earphones for commentary in many languages. As we only had 1 1/2 days in London, we did one route, switched to another route (didn't get off the buses) and the next day took the 3rd route to Tower of London then finished that route. The Orginal bus company offered (pay the conductor) 3 GBP fish & chips at Sherlock Holmes pub (on their route). With the HOHO ticket you got a river cruise. I bought the tickets online and save a few GBP.
We did the London Eye, well worth the money. I bought online with the certain time ticket. We got there early, and was able to switch our time. If you don't pick this type, can be a long line up.
The second time, I bought the Travelpass for travel on the city bus and tubes, we used this allot. The bus does not take cash. Some people use the Oyster card for bus & tube travel for an alternative travelcard scheme. Check this site;
www.londontoolkit.com on how to use this card.
I bought the above attractions online and save a few GBP on each. I felt that when we were in London, we weren't spending that much since I had bought tickets before leaving. I also watched the GBP rate and bought some when the rate went down a little.
We used a car service (
www.justairports.com) to take us from the airport to the hotel. It was nice to get met at the airport and be drivern to the hotel after a long overnight flight. Some people take the tube from the airport. To get a quote put in your hotel's postal code - 2 letters and number (our hotel's postal code was SW1), price is based on size of car and distance.
We stayed both times in the Victoria area of London. It was close to Buckingham Palace, the Mews, The Mall, restaurants/pubs,stores, grocery store, HOHO buses, regurlar bus, Victoria Coach station, Victoria train station. In that area, here are some hotels that I have read about, Premier Inn, Comfort Inn, Holiday Inn, Thistle Westminster, Luma & Simone B&B. We have found that the rooms are small compared to what we are used to here and most do not have A/C.
As a tourist, you can get some of the VAT tax back at the airport or by mailing it in. The VAT refund is good on things you can bring back home, not good for food, restaurants, or hotels. At the store, ask for the VAT refund form, they will fill it in and hand back to you with an envelope. The store takes a commission for this. I had bought some clothes at Marks & Spencers and the next day remembered about the VAT refund. I went back to the store with my receipts. They filled out the form and asked if I was buying anything else in any of the stores as they charge a commission and if buying more to do it all together and save on the commission. Some stores will do the VAT refund only at a certain $ amount. Take your VAT form and your store receipts to the office at the airport. They will refund in cash or they will mail it in and will be credited your credit card.
