Staying concierge level was Robert's request. His main interest in it was the WATER. We had stayed on that level in '09, at the Disneyland Hotel, on DVC points (can't book that level like that anymore, sad), and it was our best trip to that date and beyond, mainly because we were *hydrated*!
Paying 2.50 for a bottle of water isn't going to happen often for us (though sometimes it's worth it, like our Halloween Party night last September at WDW, when everyone was dying of thirst but no one was doing anything about it, so I bought 3 big bottles of water for $10 and we all shared them), and while the cups of ice water you can get are great...it does take time waiting in line for them, and that's annoying. Plus, more often than not we are handed very very small cups which means we can't just go about our way, but we have to drink and refill, etc, until our thirst is erased.
We didn't know we'd have the rental car for that one day, not until shortly before the trip. Honestly, if I could find a great deal on a rental car, I'd rather pay that and the parking fee, and NOT book concierge, and just go buy a case or two of water!
But it was actually a nice experience. I had something like 2 cappucinos in the morning and a nice big decaf one in the evenings, ONE night they had vegetarian egg rolls, and the rest of the time it was fruit for us and bagels for the guys and a muffin for me and waters. Since you actually have to ask for the waters at PPH we didn't get as many as we did in '09, but they might have changed the self-service-from-the-fridge at DLH as well.
It also wasn't horrendously higher than a base rate (though higher than I wanted). I used their Winter discount, which never varied from the AP rate, so it was as low as I could get it. They also have DVD players, and DVDs for free-rental from the lounge, and that was lovely, since we actually did choose to enjoy the room two evenings.
