Might be good to ask "is there an alternate place guests may watch the fireworks?"
I was thinking of staying there the 16-18th, and while its not a huge concern to me that the buffet has me locked out of the lounge for a while, i *would* like to ensure I have a view. Either a good harbor view room on a high floor, or roof access, etc.

Totally unrelated side note: Manager at Embassy Suites Tampa Harborside opened up the roof for a few of us to see the mock invasion of Tampa Bay during a military expo last year. Great service, totally fun treat.
