HI,
Last may I stayed at POR with 5 people and we stayed at AB. I loved it. My youngest DD slept on the trundle bed and was very comfortable there. We originally went through SOG to get POR but after some research I found I could book the room cheaper through WDW with one of their discount codes. We took the bus to CR to buy our park hopper tickets. It really wasnt a big deal to make the extra trip to CR to get them, we saved alot of money buy using the stars and stripes passes. After we bought our tickets we went to blizzard beach, since at that time it didnt open til 11am. It gave us time to get to CR, buy our passes and still get to BB before they opened. The trundle beds are not bad, anyone under 5 feet tall can sleep on them without any problems. My youngest DD was 9 when we were at POR and she loved the trundle bed and slept very well. She is a tall 9 yr old but still under 5 feet....but barely. she is almost as tall as me. Have fun... wish I was going with you.
