From the safety of my kitchen. A few days ago, I signed on to Virtual Tours. This is all over the World, and is people who would normal do guided tours around their cities.
Yesterday, I went to Lima and today I have been to Split on a tour around the very very old Roman City built there. The guides are very knowledgeable, as it is their normal job. It is free to belong and free to go on any tour, but like any tour you can leave a tip at the end if you wish. Lima had 819 guest doing the walk, and Split had 588.
There are some lovely tours for St. Valentines Day, but they are filling up fast. I have got a couple more booked, Edinburgh - The good the bad and the ugly and 23rd February, "Hidden Secrets of Venice"
and 19th February "A tour of Greenwich Village, NY"
Have a look, there maybe something that appeals to you somewhere in the World. Mrs Bouquet
