I am taking my 2 yr old right before she turns 3 so we don't have to pay for her hopper ticket or character meals. We also just moved into a new house so I cut corners and looked for the best deals, rebooked my rental car 3x and rebooked Southwest 2 times for the lowest price...
First night at a cheap hotel or All Stars - still undecided. No more than $77 including taxes.
Old Key West one bedroom villa - $900 including taxes for 8 days
(I could have gotten a studio for $750 but chose the extra for separate bedroom and kitchen)
Southwest rountrip plane tickets: 3 for $338 including taxes
rental car (full size) from Dollar: 8 days for $179 including taxes/charges
2 adult 7 day hopper plus (4 extra days) passes: $628 including taxes.
I guess we will spend no more than $1000 for food, 2 character meals and some minor extras.
This in total is no more than $3000 for 9 days 8 nights taking into consideration we will only be using half of our hopper passes which will reduce next trip. It pays to buy the biggest hopper ticket if you plan to go again. They never expire or you can resell the extra days on ebay. We are taking 1 or 2 rest days to actually relax by the pool and do downtown disney etc.. We are also going grocery shopping for cereal, frozen waffles for breakfast, lunchmeat, pb&j for afternoon dd's nap breaks and some small snacks, water etc.. to bring w/ us to save money. I also will be taking individual packs of Crystal light and asking for free water to save on drinks. dd drinks water all day or very diluted juice anyway so that helps too. I have purchased 75% off little toys and stuff at
Disney Store to give dd here and there to make her feel like she is getting gifts there. That saves a ton of money!!
Well hope some of this helps you! In my opinion, it pays to look around and find the best deals. Good Luck!!!
