I don't even bother to get a refund for the cancellations of my reservations thinking this may somehow help the National Parks budget a little with their progressively reduced budget.
Also, noticed private concessionaires operating inside national parks and forest escalating the fees and charges year after year -- with no visible signs of improvements in the facilities, better maintenance nor services.
What's next? Oh yeah, opening up these national patrimonies to oil, lumber and mineral exploitations.
