DD's birthday is the first week of February so we've been down at WDW for three years straight. ADRs needed? Definitely for anything popular! The cheerleaders/their families are there and it can get busy at times in restaurants such as Ohana, Park Faire. We
CRT and an adr is a must for it.
Remember, if you make adrs and decide not to go - you can cancel it the same day.
Early February is a great time to go - have fun!
