okey so some of this info is in another thread..but this is a completely different question...
&it might be a little long but i could really really use the advise

so if you can, please bare with me
okey so for graduation my dad (who is a pilot for southwest airlines) got me and 3 friends passes to anywhere in the U.S. , or at least any city with a southwest airport
so me and my friend [we're both 18]are taking our two guys[who are both 20] with us and we cant quite decide where to go
we're pretty set on going to florida! and for a while we were looking into south beach and then ft lauderdale...buuut we couldnt find a hotel in those areas that let under 21 yr olds check in
soo we just started looking into daytona beach, which has hotels that we can stay in
buut im just curious how daytona is for our age group?? if anyone has any kinda advise or personal experience with daytona or advise as to where we should spend 4 days vacationing, i would greatly appreciate it!
[basically, we're looking for a city with nice beaches & a fun night life for our age group ]
