Hello Chloe. Which date are you travelling on? I'll be the TM all being well on the tour leaving 16th October.
Its great to read all of the comments about this fabulous tour, it is certainly one of my favourites and you're right, there is such a lot to do.
I'm not sure what you have booked in advance already, but I or your TM will go through the optionals with you, especially the safaris in Kruger as I know it can be quite confusing. We book the safaris there as we can explain the different options/variations you can do and also it may vary with the time of year/weather etc. As someone said it is sometimes possible to extend the included morning drive into a full day by adding the afternoon optional, and then also doing a full day on the 2nd day at Kruger.
Chobe is my personal favourite optional too and if you enjoy wildlife, I would definitely recommend this. Again it can be booked in resort and I or your TM will explain more once you are on tour. The comments on here with regard to the water over Vic Falls are correct, it is low water in October, however I love this too as you can the beautiful gorges and take the chance to visit Livingston Island, a fab excursion but only possible at low water.
I hope this helps a little! You have chosen a fantastic holiday and hopefully, if our dates are the same and I am on the Oct 16th tour we'll meet at Heathrow.
All the best
Lynne
