I will get planning eventually, just can't do it 6 months in advance.
If Xmas was anything to go by we should have no problems, the parks were to capacity but still got ADR for Boma a couple of days in advance, got there about 30 mins early, straight in lots of empty tables. Talking to Guest services in MGM(made another ADR for trails end 3 hours before we ate) she said the parks were really busy but resort restaurants were quiet.
Now if they got online ADR system working it would be an incentive to get sorted and try it out, when the time comes.
