I was at Walmart and picked up the last 2 Brita fill & go bottles w/filters, since it has been recommended by many on this board. They were marked down to $5.00 and the 2 pack of filters was marked down to $4.00. My question is, where do you fill the bottle from? The sink in the hotel room? What about in the parks? Do you fill from a water bubbler or do you ask for ice water at counter service restaurants? How cold is the water from a water bubbler? I can't stand water that is not really cold. There will be 5 of us (2 adults, 3 kids) so 2 Britas won't be enough for all of us, and I do plan on bringing some chilled juice boxes for the kids, but I wonder if I would be better off just bringing some chilled disposable bottles in a small cooler instead of the Britas. Any advice?
