Managing to keep such a large group with 8 kids under 12 and several teenagers and young adults (2 sets of parents, older generation and younger generation) is really tough, we finally agreed to split. I am now on the way to S. Petersburg on an overnight train with 4 teenagers and a young adult.
It was extremely difficult to book online (even though I have a Russian debit card that someone loads for me). When I finally thought I figured out the right train for us, payment failed repeatedly. So I asked someone who helps us to book for us. It also took him a while, especially since I didn't want my daughters to be in the same room with strangers.
According to Yandex a taxi ride to Leningradsky train station should take 10 minutes, but we had a long wait for a "minivan" (Citroën C4). I was told by locals that I should plan to arrive at the station at least 40 minutes before departure, so when the traffic on the block of the station seemed like we wouldn't even have 10 minutes if dropped off at the entrance, I used Google translate to communicate with the driver that we only have 15 minutes to departure. He dropped us off about 200-300 ft away from the station, and a brisk walk it was.
Security is the good old type, no TSA nonsense. Just bags through x-ray machine along with metal belonging. My Apple watch and my Shabbos belt keys didn't trigger the metal detector. Departure sign was clear and bi-lingual, and off it was to track #3. We found our cars, didn't have to show tickets, but had to show passports.
Train supposedly is air-conditioned and has wifi. But at lowest setting I am still too warm, and wifi is unusable, so it's back to mobile data.
Conductor (or attendant, or whatever it is) came and asked for our passports. I ask her in Russian for very cold sparkling water. She says the don't have. I say cold. Nothing doing. Only room temperature. Ice? Unheard of. I motion to show her that I'm hot, so she tries to lower the A/C setting, only to discover that it's already on lowest. She tells me what time breakfast is served, and I ask for kosher. She asks if I want Kasha. I say no, Kosher. Jewish Religious. Nothing doing. She offers drinks and all I ask for is cold sparkling water.
TBC.
