We're doing a Zion-Bryce-Page trip next week (we're from Cambridge, MA!) and will be in Page to see Antelope Canyon, but will have an additional day (starting around 11 am) that we had planned on using to see Lake Powell. After scouring these forums, I think I've narrowed it down to either the Glen Canyon float trip (starts at 11 and goes till about 4:30 including the bus ride back) or renting a motorboat for half a day from Waheap.
Can anyone compare these two experiences for me? How are the different? Which one will have more spectacular scenery? Do you have time to get to and explore interesting side canyons on Lake Powell with just a half-day rental? (And if so, how do we figure out where they are and which ones to try to see?)
Thanks so much for any insights!!!
