I'm really pleased you've booked it lemur and with a table seat - they all have sockets. You might be really lucky and have a whole table section to yourselves.
THe guards that go up and down, are usually really nice when it come to children, so its really worth asking if there are any free 4 seat table places anywhere, if you don't manage to get that anyway.
Also, please, do check out the carriage with the disabled sticker on it - usually nearer the front of the train, although I think there are 2. Even if you have allocated seats, if the table seats directly next to the disabled foldaway chair area, it really is more comfy,loads of space infront of the table - with socket! and you won't be moved on, unless someone with a wheelchair does get on. I say this as you can put up your buggy, have your bags there too, or at least your food & 'entertainment" bag and be more comfortable with more space. Its not doing anything wrong- as I said in my earlier post, I checked it out many times with various guards,and the answer was always, its fine unless genuinely "needed "
And again, my DD was not a napper ever really come to think of it- anyway, I did used to put her in her buggy,recline it, face it to the window and she'd doze off with the motion of the train. then I got to read my magazines!
You might actually find you have fun. I honestly didn't dread it ever, even when DD was very mobile and needed lots of entertaining! I didn't have a DVD player, but not sure she'd have watched anything, she was far too interested in everyone else.
I can still recall some of the kindest people i've ever met, being on my own, on those trains. Also having some really lovely quite intense one to one 'sessions' with DD, playing with a jigsaw or reading, or anything I'd brought.
I recently found these BTW and they are fantastic, in the car, anywhere really, so I'd recommend getting some.
Crayola magic pens
In that link, it also shows similar magic painting, too. As you will see, there are loads of different books to get to use with the pens, infact I think they all just come as packs. BUt DD has loved them. It says age 3+ but, i'd say any child able to scribble will have fun with them. Well worth the money IMHO
Sorry for such a long post, but I'm a really seasoned train traveller, on long journeys, and as said, I did it on my own, no probs - except when she was a baby & I needed a wee... I even had other passengers, i'd got talking to, holding her up by the window and talking and bouncing her etc at times just to give me a break to eat or something. Always in view - obviously.
IF you've read on, thankyou! and I hope some of it helps
Have a great time and best of luck with your adventure. Trust me, you will do it next time too
