Now it's time to calculate prices.
Day 19: train from Amsterdam Airport to Den Haag Centraal - 9,60
Day 20: train from Den Haag Centraal to Arnhem - 20,40
Burgers Zoo - 22,50
Back from Arnhem to Den Haag Centraal - 20,40
Day 21: train from Den Haag Centraal to Best - 19,60
BestZoo - 11
Transport (I hope to find one less complicated than the one provided by AWP!) from Best to Volkel - approx 11,51
Zie-Zoo - 9,75
Back from Volkel to Den Haag Centraal (I dind't found any info, I suppose it will be around 20)
Day 22: train from Den Haag Centraal to Zwolle - 21,80
Zwolle bird market - 10
Back from Zwolle to Den Haag Centraal - 21,80
Day 23: train from Den Haag Centraal to Apeldoorn - 20
Apenheul - 22,50
Back from Apeldoorn to Den Haag Centraal - 20
Day 24: train from Den Haag Centraal to Amsterdam - 12,80
Artis - 21
Natural History Museum inside the aquarium building of Artis - I hope it don't ask for a separate fee!!
Hortus Botanicus 9,50 (the most expensive botanical garde that I've knew ever!!!)
Back from Amsterdam to Den Haag Centraal - 12,80
Day 25:
Train from Den Haag Centraal to Harderwijk - 18
Dolfinarium Harderwijk - 28,50
Train from Harderwijk to Den Haag Centraal - 18
Train from Den Haag Centraal to Bruxelles-Midi - 9
Day 26:
Train from Bruxelles-Midi to Cambron-Casteau - 9,90
Pairi Daiza - 34
Train from Cambron-Casteau to Bruxelles-Midi -9-90
Otherwise, if I manage to get the B-Excursion with combined train-entry ticket, suggested by migdog, I will save some money, but I calculate at maximum for preventing inconveniences...
Day 27:
Train from Bruxelles-Midi to Antwerpen - 7,70
Antwerp Zoo - 26,50
Train from Antwerpen to Bruxelles-Midi - 7,70
Day 28:
Bruxelles Natural History Museum -7
Combined train-bus from Bruxelles-Midi to Brussels-Charleroi South (Airport) - 15,90
The food, plus a margin for small transports inside city, maybe some thing to buy, some invit to dinner to my hosters, etc - I hope to have enough with 200 € (9 days)
Total: 477,26 (trains + zoos) + 200 (food + items) = around 700 €
I hope it worth the effort! The rest will depend on the luck and how collaborative are the animals - and the zoo staff for let me seeing something behind the scenes (Tataupa tinamou and yellow-headed gecko at Burgers, giant squirrel, woolly opossum and Virginia opossum at Best, egyptian mongoose, giant pouched rat and steppe marmot at Zie-Zoo, rare amphibians at Antwerpen, palestine mole rat and raptors at Pairi Daiza). Probably I will not see any of these animals, but even without these will be a nice experience. I'm illusionated

Wish me luck!
