I can go up high but i do sometimes feel a little queasy, depending on where i am but it's manageable as i have been on the London eye and at the top of the Eiffel tower!
Do you prefer hot weather or for it to be a bit cooler?
Hmm, somewhere in between...but maybe cooler i guess..if it's colder you can always add more clothes but when it's hot there's only so much you can take off!
Oh man I love the water! My parents introduced me to water very early on and I was fearless! I was on swim teams through my youth till high school, LOVED it! I wish I had a pool to do laps now, it is such good exercise!
