The Patch for BV solves that bug:

Complete list of changes:
Note: Not all fixes will take effect on existing The Sims 2 Bon Voyage saved games. If you have an existing lot, Sim, object or neighborhood that does not seem to be improved by this patch, we recommend that you replace the affected object, or create either a new family, lot or neighborhood, depending on what is affected by the bug.

* Sims will no longer have the option to call vacation service NPCs after acquiring the business perk "Head for Numbers" which was causing a crash.
* Sims will no longer have the option to "Call Taxi" using their cell phones if they have driven to the community lot with an own-able vehicle which was causing a crash.
* If the Sim misses the shuttle, it will no longer return to a vacation lot without the Sim at the end of the vacation. Sometimes, this caused the vacation lot to become unusable.
* Game will no longer create new vacation NPCs each time a lot is visited which was causing many issues due to character file overload. Any existing extra NPCs will be unlinked and their character files greatly reduced in size.
*Periodic Events Controller will no longer loop twice per hour through each neighbor which was causing extreme lag on certain machines.
*Autonomous water-balloon and snowball fights have been tuned so the interaction will occur less frequently."
