Planning Livadia as the focus of a tour sounds like a great idea! My friend Vladimir says so much more of the palace is open to tourists now since I was there. And the outbuildings you refer to . . . would those have been where the servants and attendants resided?
Yes, flying can be . . . interesting! We flew from St. P via Aeroflot, and I've never been so frightened in my life. (No empty phrase, that!) In fact, I had an extended "conversation" with the Grand Duchess Olga Nicholievna, promising that if our plane didn't crash I'd be sure to write her story. (Alas, am still in the process--no lightning bolts yet, though.) We were onboard a (supposedly) reconverted military plane and it screeched, rattled and vibrated the entire time; you couldn't carry on a conversation with the person sitting next to you unless you shouted. Smoke kept wafting from the restrooms and nothing seemed completely secure, including our seats. On the other hand, after our Yalta stay we flew from Simferabol to Kiev via a private airline--according to our guide, the first one of non Communist Russia--and the experience was delightful. So, you never know . . .
In addition to Livadia, the town of Yalta is interesting, as is Chekov's home and the estate where Churchill stayed during the Yalta conference. The walk up to Swallows Nest is also intriguing (and a good stretch of the legs!), but if I had it to over I would have spent more time at Livadia Palace. Also, other estates and palaces are within driving distance; Vladimir sends me information about them from time to time. It's a beautiful area--much like Laguna Beach, CA, which is just a twenty minute drive from my home . . . no royal estates in Laguna Beach, though! But in Yalta, as in Laguna Beach, both palms and pines are in abundance, the sea sparkles, geraniums and other flowers color the area, and the overall feeling is one of holiday and relaxation.
