We have the choice of the following trains between Oberoi Jaipur and Agra next week:

9:10-13:10 - 4 hours classes available: 2a, 3a
12:50-16:50 - 4 hours 3a
15:00-19:30 - 4.5 hours 2a (waiting listed), 3a
17:37-21:06 - 3.5 hours chair class

The latter train is quicker because it stops at Idgah, 2km from Agra fort, but for some reason it takes 20-30 minutes to do this last distance.

We are travelling with our children 4, 9.
