At least her ZJ was nice enough to give you some advance warning the water pump was going out and taking up half your Sun where you could work on it where you want doesn't sound like that much of an inconvenience to me.
I remember driving my wife's 93 4.0 XJ on the freeway when w/o warning the temp quickly skyrocketed and quickly got off the next exit as the lights started dimming. Ended up in the parking lot of Tequila Mama's at 11pm on a Sat night with steam rolling out of the engine compartment. The bearing/water pump had come apart shredding the belt and boy did the drunks think the steam was neat!
Luckily my daughter was following us to give us a ride home. The next day (Sun) I replaced the pump/belt where it sat when all of the sudden a huge snowstorm rolled in with high winds. Couldn't stop and had to tie the hood down on the latch so the winds wouldn't bring it down on me. Couldn't hardly find the right tool in my toolbox because of the sudden heavy snow. Now that's an inconvenience and finally got it fixed. The whole time while working on it my wife was sleeping in my cozy 96 ZJ with the heater on.
