How much would a trip to Ireland cost(rough estimate)?

I am going to Ireland this summer too, and per person, my family and I are spending, around $5000. It may seem like alot, but were staying at 5 star hotels, and going out to dinner almost every night. Plus were with a very expencive travel company. If your 18. the best guess would be that you spend around 1500 to 2000. good luck!
