Vacations

I haven't had any Sims go on Vacation for some time and I tried it recently but not working. Taxi picks up Sim, shows plane flying to Twikkii Island, then it loads the selected lot. But after that nothing, my Sim doesn't get to the selected lot, no one there at all. When I get out of the neighborhood and go back to the original neighborhood, the Sims house has a dark green diamond above the house, not a light green or yellow. Can't enter the house because it says they are on vacation. I can go to a neighbors house and click on the subject house and it asks if I want to play it. Go there and either the family is there or a taxi arrives and they come in. But when I shut down and reload another time, same thing, dark green diamond and says they are on vacation. Any suggestions ?? Is there a Patch for Mansions and Gardens Stuff Pack ?
