I've compiled a RTW itinerary below that I want to do in 6 months or so. I intend to start off in London and end in Buenos Aires, I will be staying back in Buenos Aires to study spanish for 6 months so not using the Buenos Aires-London sector. I would appreciate feedback on the feasibility of this itinerary in a 6 month time period and also any opinions on any of the chosen destinations (worth it/not worth it etc.).

The * indicates a RTW point. I plan to use local cheap flights (Easyjet/Air Asia/Jetstar/Ryanair etc.)/trains/buses for the other sectors.

London*(UK) [Start point]
Ireland [Dublin]
Scotland [Glasgow]
Portugal [Lisbon*]
Spain [Madrid, Barcelona, Valencia, Ibiza, Alicante, Gibraltar]
Andorra (actually Madrid->Andorra->Barcelona...)
Morrocco [Tanger, Casablanca, Fez, Marrakesh]
Switzerland [Zurich*]
Greece [Athens*, Santorini, Crete]
Egypt [Cairo*, Alexandria, Luxor]
Jordan [Amman*]
Syria [Damascus]
Lebanon [Beirut]
Israel [Tel Aviv] (ret to Amman via the West Bank)

India [Mumbai*, Bangalore]
