Hope I can be forgiven for posting this on LPside but would appreciate any feedback. 2 lone mothers and nine children (!) want to leave Germany (on-going dilemma) to visit London for 3 days in August to do all the tourist things..travel, group tourist things seems viable but where do we stay that is cheap and safe...any ideas? Also is the underground daily travelcard the cheapest alternative for a group of 11? Thanks for any suggestions!
