We ran up about $50 in phone charges in a week but the peace of mind my wife got from speaking with the petsitter was worth the money. It's nice to have the option of making a call if you absolutely have to. I turned the phone back on in the Ft. Lauderdale airport and it rang instantly. It was Mastercard wanting to know if the $1,000 just charged to my account was legitimate. The phone charges paled in comparison with spa charges, tips, gift shop, etc!
