Does that mean you already paid 10k? I remember your upcoming vacation to Disney World was 15k.
I would not pay 15K for Disney...I'll go somewhere else.
The last time I was in FL, we did the trip on a budget (save as much as possible). Airline was under $400 for 4 people roundtrip (I was lucky to find a great deal) and I paid full price for Discovery Cove (all day meals and drinks included) and got free admission to Sea World and Sea Aquatica AND a great deal to Bush Garden. Car and hotel (similar to Holiday Inn, La Quinta, etc..) was $300 for the four -five days. I spend less than $1500 for the entire trip for 4 people.
