I am booking a trip for early June. I need to decide between AoA Standard Room (Mermaid) vs. PO Riverside. It is for a party of 4 (two adults, plus 10 & 13 year old daughters). The price is nearly the same (PO is eligible for the current promo and AoA is not). We are staying for 10 nights. Using WDW transportation exclusively. We have been to WDW several times. We plan on visiting the water parks 2-4 times in addition to the parks. We have stayed at PO previously but never at AoA. Any feedback is appreciated.
