Hello! I booked a 4-hour tour with a London guide directly via email - found his name on guidelondon.org and reached out. As we booked directly with him, should we plan on giving him a tip the day of our private tour? What is customary and expected?
Also booked a tour via Tours By Locals, and their website advises that the guides set their prices, and tips are not needed, but says if we would like to tip, the guide may accept it. What is an appropriate amount of tip for a full day tour of Windsor Castle and Hampton Court? We plan to leave reviews about our good experiences.
Appreciate any advice.
