I've warmed more to Tom and Caroline in the last two episodes as they've relaxed into the flow.
The brothers are still my favourites. There's warmth and humour to them.
I can understand Sionned's overwhelm, and Fin did well getting her through the urban areas when she went into shut down.
I like Elizabeth, but Letitia's reserve is frustrating. I want to see them relax with each other. I love the travel which is the main part of the show, but there is the personal development side to it, and on epic journeys like that, you do test/ develop the relationship and learn a lot along the way.
Budget is probably less of a focus this time because the costs are relatively low and there's no significantly more expensive countries to mess up their budgets.
Train travel is hard to do at short notice in India. I used trains more in the north with a few days notice to get a sleeper. In the south (recovering from food poisoning) we hired a driver for the simplicity and comfort which was relatively cost effective.
Nepal is very much bus country. You get used to the perilous edges... and burned out wrecks across the hill sides. Although the crashed bus with people still getting out was somewhat alarming... it must only have been a few minutes ahead of us!
The scariest road was in Tibet coming away from base camp and there was an oncoming vehicle on the narrow road. No passing points for ages. We were told to get out of the 4x4 and wait while the two drivers passed each other with barely an inch to spare between the side of the mountain, the other vehicle and the side of the cliff with total precision. It was nerve wracking to watch!
They got lucky on the clear weather at the Taj Mahal; it's normally rather smoggy.
