Pop is such a fun resort! It is wonderful to see all the nostalgic icons everywhere. We love the view across hourglass lake from the standard rooms looking toward AoA. It is so nice to be able to walk across the bridge to AoA and sample their food court as well as take some awesome pictures!!! Love the photo ops everywhere. You get the advantage of AoA's over the top theming without paying the over the top prices! How awesome is that?
Having your Mom along will be such a nice treat! You will be able to enjoy the very best that WDW offers - time with loved ones in a happy place. Memories like that are irreplaceable! Staying on Disney property at such a great value resort saves tons of $$$ for extras. You can do a special activity such as the
MVMCP, or a behind the scenes type of tour. Some of these are fantastic! Celebrating your Mom's birthday will be so special..
The food court is great at both POP and AoA. POR does have a TS restaurant, but it isn't one that we care to frequent. We usually eat our 'nice' meals in the theme parks or at the luxury resorts, anyway. Staying at POP will free up enough money to take taxis to resorts for dining without any guilt! Score!
Love the great bus service at POP. It is so convenient and nice that you get to the theme parks so efficiently and quickly. We have stayed at luxury resorts where the bus service was much worse than what we experienced at POP. POR is nice, too, but it's bus service is not as good as that at POP, IMO. Try to focus on the positives staying at POP and forget about POR. You pay a lot more at POR for what is essentially the same product - a comfortable hotel room in beautiful surroundings.
With the savings of staying at a value this trip, perhaps you can squeeze in another trip later or stay extra days.
You can still try for an opening at a moderate and change if it comes available. But I'm not sure if I would bother. POP is fantastic! You will really have a great stay here!
Enjoy! Yay! You're going to WDW and your MOM is coming too!!
