My family and I (DH & DD14) usually stay a week at a WDW resort. We have never used PHs before for a week trip. We go to one park per day, and if it's our HS day, we take a good, long afternoon break. We typically get to the parks early, take an afternoon break, and head back until we can't stand any more. I plan well and obsess over ADRs and FPs, but I have never felt we've been missing out by not hopping. I try to follow crowd calendars, but as long as we can ride whatever we FP and a couple more, we're okay. And I always make ADRs, so we don't worry about where we're going to eat.
Now, DD and I did just get back from a long weekend trip. I couldn't imagine going to WDW without riding TSMM, but we also wanted to go to Pandora at night and see HEA, so we got PHs. It was fun, but I couldn't handle if for an entire week. We had 2 park days. On our first day, we hit HS just to ride TSMM a couple of times, then walked over to Epcot for F&W lunch. We still had a short afternoon break, and then we headed to AK for the evening (I really wanted to try to get to MK that day, just to say we did all 4 parks, but they closed early for a
MNSSHP). The following day, we started at Epcot late morning and had lunch at VN, had our break, and then headed to MK for HEA. I could see DD and I doing it for a longer trip, but I don't think DH would like it. And I have to admit, I was confused myself! Our first evening when we were walking to the bus stop to head to AK, a AK bus was pulling up. I told DD "We don't need to hurry, we're going to Epcot". I didn't realize until the bus drove away that we were heading to AK. I did it the following night, too. Oops!
