Hello,
My mother in law is taking my twin 18 year olds on an 8-day trip to London in July. She would like to book guided tours that will help skip lines at the major attractions, and possibly provide car service as well. She would like to take them to all the most important tourist sites. Anything cool and off the beaten path would be great as well since they have a good bit of time.
Any suggestions on where to look for tour guides or names and contact info of great tour guides is much appreciated! They don't have to provide car service but walking long distances is challenging for her so it could come in handy.
Thank you so much!
